- Move drivers for really old legacy hardware to staging. Those are
using obsolete media kAPIs and are for hardware that nobody uses for
years. Simply not worth porting them to the new kAPIs. Of course,
if anyone pops up to fix, we can move them back from there
- While not too late, do some API fixups at the new colorspace API,
added for v3.19
- Some improvements for rcar_vin driver
- Some fixups at cx88 and vivid drivers
- Some Documentation fixups

This driver hasn't been tested in a long, long time. The company that made
this chip has gone bust many years ago and hardware using this chip is next
to impossible to find.
This driver needs to be converted to newer media frameworks but due to the
lack of hardware that's going to be impossible. Since cheap alternatives are
easily available, there is little point in keeping this driver alive.
In other words, this driver is a prime candidate for removal. If someone is
interested in working on this driver to prevent its removal, then please
contact the linux-media mailinglist.

Merge tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Two new dvb frontend drivers: mn88472 and mn88473
- A new driver for some PCIe DVBSky cards
- A new remote controller driver: meson-ir
- One LIRC staging driver got rewritten and promoted to mainstream:
igorplugusb
- A new tuner driver (m88rs6000t)
- The old omap2 media driver got removed from staging. This driver
uses an old DMA API and it is likely broken on recent kernels.
Nobody cared enough to fix it
- Media bus format moved to a separate header, as DRM will also use the
definitions there
- mem2mem_testdev were renamed to vim2m, in order to use the same
naming convention taken by the other virtual test driver (vivid)
- Added a new driver for coda SoC (coda-jpeg)
- The cx88 driver got converted to use videobuf2 core
- Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc
cores
- Lots of other fixes, improvements and cleanups on the drivers.

This patch is basically produced while testing a tool that
Joe Perches sent upstream sometime ago:
https://lkml.org/lkml/2014/7/11/794
I used it with those arguments:
$ reformat_with_checkpatch.sh drivers/media/usb/em28xx/em28xx*.[ch]
It actually produced 24 patches, with is too much, and showed
interesting things: gcc produced different codes on most of the
patches, even with just linespace changes. The total code data
remained the same on all cases I checked though.
Anyway, provided that we fold the resulting patches, this tool
seems useful.

Drivers that use dvb_attach can have just one exported symbol,
or they will cause compilation breakages depending on the
selected frontends.
As Jim reported:
drivers/built-in.o: In function `technisat_usb2_set_voltage':
technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio'
make: *** [vmlinux] Error 1
That happens because, on his configuration, the configuration
is:
CONFIG_DVB_USB=y
CONFIG_DVB_STV090x=m
Luis proposed ar way to fix, but that would just force the
STV090x to be selected, even if one wants to use a device
with a different frontend.
Instead, let's do the right thing: move set_gpio to the
configuration structure and fill it during dvb_attach().
This way, the driver can still call it, and dvb_attach()
will load stv090x module only if the device really needs it.

* Silicon Labs Si2168-A30 demodulator
* Silicon Labs Si2146-A10 tuner
I don't have the remote, so the RC_MAP is a best guess based on the pictures of

The cause is that uvc_status_cleanup() is called after usb_put_*() in
uvc_delete(). usb_put_*() removes the sysfs parent and eventually
removes the children recursively, so the later device_del() can't find
its sysfs. The fix is simply rearrange the call orders in
uvc_delete() so that the child is removed before the parent.

Unfortunately, on devices that have multiple interfaces, udev->dev
points to the parent device (usb) instead of the cx231xx specific one.
Due to that the logs don't look too nice, as they'll print messages
as if they were produced by USB core:
usb-1-2: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces
Instead of using the name of the parent device, let's use the name
of the first cx231xx interface for all cx231xx sub-modules.
With this path, the logs will be nicer:
cx231xx 1-2:1.1: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces

Don't need to show when it starts or stops. Just print lines
when devices are found.
After the changes, the output for i2c scan will be like:
usb 1-2: i2c scan: found device @ port 0 addr 0x40 [???]
usb 1-2: i2c scan: found device @ port 0 addr 0x60 [colibri]
usb 1-2: i2c scan: found device @ port 0 addr 0x88 [hammerhead]
usb 1-2: i2c scan: found device @ port 0 addr 0x98 [???]
usb 1-2: i2c scan: found device @ port 3 addr 0xa0 [eeprom]
usb 1-2: i2c scan: found device @ port 2 addr 0x60 [colibri]
usb 1-2: i2c scan: found device @ port 2 addr 0xc0 [tuner]
usb 1-2: i2c scan: found device @ port 4 addr 0x20 [demod]

Now that we're using dev_foo, the logs become like:
usb 1-2: DVB: registering adapter 0 frontend 0 (Fujitsu mb86A20s)...
usb 1-2: Successfully loaded cx231xx-dvb
cx231xx: Cx231xx dvb Extension initialized
It is not clear, by the logs, that usb 1-2 name is an alias for
cx231xx. So, we also need to use dvb_info() at extension load/unload.
After the patch, it will print:
usb 1-2: Cx231xx dvb Extension initialized
With is coherent with the other logs.

There are several places at cx231xx that uses printk without
any special reason. Change all of them to use dev_foo().
