Commit f9c6cea0b3 ("ibmvnic: Skip fatal error reset after passive init")
says "If the passive
CRQ initialization occurs before the FATAL reset task is processed,
the FATAL error reset task would try to access a CRQ message queue
that was freed, causing an oops. The problem may be most likely to
occur during DLPAR add vNIC with a non-default MTU, because the DLPAR
process will automatically issue a change MTU request.
Fix this by not processing fatal error reset if CRQ is passively
initialized after client-driven CRQ initialization fails."
The original commit skips a specific reset condition, but that does
not fix the problem it claims to fix, and misses a reset condition.
The effective fix is commit 0e435befae ("ibmvnic: fix NULL pointer
dereference in ibmvic_reset_crq") and commit a0faaa27c7 ("ibmvnic:
fix NULL pointer dereference in reset_sub_crq_queues"). With above
two fixes, there are no more crashes seen as described even without
the original commit, so I would like to revert the original commit.

DCB uses the same handler function for both RTM_GETDCB and RTM_SETDCB
messages. dcb_doit() bounces RTM_SETDCB mesasges if the user does not have
the CAP_NET_ADMIN capability.
However, the operation to be performed is not decided from the DCB message
type, but from the DCB command. Thus DCB_CMD_*_GET commands are used for
reading DCB objects, the corresponding SET and DEL commands are used for
manipulation.
The assumption is that set-like commands will be sent via an RTM_SETDCB
message, and get-like ones via RTM_GETDCB. However, this assumption is not
enforced.
It is therefore possible to manipulate DCB objects without CAP_NET_ADMIN
capability by sending the corresponding command in an RTM_GETDCB message.
That is a bug. Fix it by validating the type of the request message against
the type used for the response.

====================
net: ipa: GSI interrupt handling fixes
This series implements fixes for some issues related to handling
interrupts when GSI channel and event ring commands complete.
The first issue is that the completion condition for an event ring
or channel command could occur while the associated interrupt is
disabled. This would cause the interrupt to fire when it is
subsequently enabled, even if the condition it signals had already
been handled. The fix is to clear any pending interrupt conditions
before re-enabling the interrupt.
The second and third patches change how the success of an event ring
or channel command is determined. These commands change the state
of an event ring or channel. Previously the receipt of a completion
interrupt was required to consider a command successful. Instead, a
command is successful if it changes the state of the target event
ring or channel in the way expected. This way the command can
succeed even if the completion interrupt did not arrive while it was
enabled.

This patch implements the same basic fix for event rings as the
previous one does for channels.
The result of issuing an event ring control command should be that
the event ring changes state. If enabled, a completion interrupt
signals that the event ring state has changed. This interrupt is
enabled by gsi_evt_ring_command() and disabled again after the
command has completed (or we time out).
There is a window of time during which the command could complete
successfully without interrupting. This would cause the event ring
to transition to the desired new state.
So whether a event ring command ends via completion interrupt or
timeout, we can consider the command successful if the event ring
has entered the desired state (and a failure if it has not,
regardless of the cause).

We enable the completion interrupt for channel or event ring
commands only when we issue them. The interrupt is disabled after
the interrupt has fired, or after we have timed out waiting for it.
If we time out, the command could complete after the interrupt has
been disabled, causing a state change in the channel or event ring.
The interrupt associated with that state change would be delivered
the next time the completion interrupt is enabled.
To avoid previous command completions interfering with new commands,
clear all pending completion interrupts before re-enabling them for
a new command.

Commit 34f0f4e3f4 ("ibmvnic: Fix login buffer memory leaks") frees
login_rsp_buffer in release_resources() and send_login()
because handle_login_rsp() does not free it.
Commit f3ae59c0c0 ("ibmvnic: store RX and TX subCRQ handle array in
ibmvnic_adapter struct") frees login_rsp_buffer in handle_login_rsp().
It seems unnecessary to free it in release_resources() and send_login().
There are chances that handle_login_rsp returns earlier without freeing
buffers. Double-checking the buffer is harmless since
release_login_buffer and release_login_rsp_buffer will
do nothing if buffer is already freed.

When searching for inactive maintainers it's useful to filter
out mailing list addresses. Such "maintainers" will obviously
never feature in a "From:" line of an email or a review tag.
Since "L:" entries only provide the address of a mailing list
without a fancy name extend this pattern to "M:" entries.
Alternatively we could reserve M: entries for humans only
and move the fake "maintainers" to L:. While I'd personally
prefer to reserve M: for humans only, I'm not 100% that's
a great choice either, given most L: entries are in fact
open mailing lists with public archives.

The dwmac glue registers on Amlogic Meson8b and newer SoCs has two clock
inputs:
- Meson8b and Meson8m2: MPLL2 and MPLL2 (the same parent is wired to
both inputs)
- GXBB, GXL, GXM, AXG, G12A, G12B, SM1: FCLK_DIV2 and MPLL2
All known vendor kernels and u-boots are using the first input only. We
let the common clock framework automatically choose the "right" parent.
For some boards this causes a problem though, specificially with G12A and
newer SoCs. The clock input is used for generating the 125MHz RGMII TX
clock. For the two input clocks this means on G12A:
- FCLK_DIV2: 999999985Hz / 8 = 124999998.125Hz
- MPLL2: 499999993Hz / 4 = 124999998.25Hz
In theory MPLL2 is the "better" clock input because it's gets us 0.125Hz
closer to the requested frequency than FCLK_DIV2. In reality however
there is a resource conflict because MPLL2 is needed to generate some of
the audio clocks. dwmac-meson8b probes first and sets up the clock tree
with MPLL2. This works fine until the audio driver comes and "steals"
the MPLL2 clocks and configures it with it's own rate (294909637Hz). The
common clock framework happily changes the MPLL2 rate but does not
reconfigure our RGMII TX clock tree, which then ends up at 73727409Hz,
which is more than 40% off the requested 125MHz.
Don't use the second clock input for now to force the common clock
framework to always select the first parent. This mimics the behavior
from the vendor driver and fixes the clock resource conflict with the
audio driver on G12A boards. Once the common clock framework can handle
this situation this change can be reverted again.

'maxItems' equal to the 'items' list length is redundant. 'maxItems' is
preferred for a single entry while greater than 1 should have an 'items'
list.
A meta-schema check for this is pending once these existing cases are
fixed.

*-supply properties are always a single phandle, so binding schemas
don't need a type $ref nor 'maxItems'.
