The second parameter of regulator_mode_constrain takes a pointer.
This patch fixes below warning:
drivers/regulator/core.c: In function 'regulator_set_mode':
drivers/regulator/core.c:2014: warning: passing argument 2 of 'regulator_mode_constrain' makes pointer from integer without a cast

Current set_mode logic does not support 6030. The logic for 4030 is
not reusable for 6030 as the mode setting for 6030 now uses the new
CFG_STATE register. We hence rename the old get_status as being
specific to 4030.

With TWL6030, it is not enough to ensure that the regulator is the
group of P1 group (CPU/Linux), but we need to check the state as far
as APP is concerned as well.
Split the current is_enabled to 6030 and 4030 specific ones. This
split impacts few macros and variables as well, but sets up the
stage for further fixes to set_mode and get_status in subsequent

TWL6030 does not have remap register. The current implementation
causes value of remap to be written to state register, accidentally
causing the regulators which are probed to be switched on as well.
This is wrong as regulators should be controllable based on calls
to enable/disable for TWL regulator framework. Further, the values
initialized make no sense as well. We hence remove this from the
initalizers and also write to remap register only if the TWL
is 4030.

TWL6030 requires an additional register write to CFG_STATE register
to explicitly state that the regulator is in a certain state. Merely
associating the regulator with the group is not enough. Add the
required register field definitions and fix the handling for
TWL6030 enable/disable.

The Blackfin SPORT peripheral is a pretty flexible device. With enough
coaching, we can make it generate SPI compatible waveforms. This is
desirable as the SPORT can run at much higher clock frequencies than the
dedicated on-chip SPI peripheral, and it can do full duplex DMA. It also
opens up the possibility of multiple SPI buses in case someone wants to
dedicate a whole bus to a specific part that does not play well with
others.

Export 'max_loop' and 'max_part' parameters to sysfs so user can know
that how many devices are allowed and how many partitions are supported.
If 'max_loop' is 0, there is no restriction on the number of loop devices.
User can create/use the devices as many as minor numbers available. If
'max_part' is 0, it means simply the device doesn't support partitioning.
Also note that 'max_part' can be adjusted to power of 2 minus 1 form if
needed. User should check this value after the module loading if he/she
want to use that number correctly (i.e. fdisk, mknod, etc.).

Add rwpidforward mount option that switches on a mode when we forward
pid of a process who opened a file to any read and write operation.
This can prevent applications like WINE from failing on read or write
operation on a previously locked file region from the same netfd from
another process if we use mandatory brlock style.
It is actual for WINE because during a run of WINE program two processes
work on the same netfd - share the same file struct between several VFS
fds:
1) WINE-server does open and lock;
2) WINE-application does read and write.

- Remove the memset in the lpfc_sli4_remove_rpi_hdrs call.
- Correct swapping of SGE word 2 relative to offset value
- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override

- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.

the sas_deform_port() path because that prevented scsi sync cache
commands from being issued when the driver was unloaded. However, this
allows true device gone notifications (as signaled port phy events) to
trigger sync cache commands to devices that are known to be unreachable.

Don't do it. The normal callers all pass a real avd pointer, and this
helper function is incredibly hot. So don't make avc_has_perm_noaudit()
do conditional stuff that isn't needed for the common case.
