The tvp5150_write() function can fail so don't return 0 unconditionally
in tvp5150_s_register() but propagate what's returned by tvp5150_write().

The tvp5150_write() function calls i2c_smbus_write_byte_data() that
can fail but does not propagate the error to the caller. Instead it
just prints a debug, so callers can't know if the operation failed.
So change the function to return the error code to the caller so it
knows that the write failed and also print an error instead of just
printing a debug information.
While being there remove the inline keyword from tvp5150_write() to
make it consistent with tvp5150_read() and also because it's called
in a lot of places, so making inline is in fact counter productive
since it makes the kernel image size to be much bigger (~16 KiB).

Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with
following components:
USB bridge: Empia EM28274 (chip id is the same as EM28174)
Demodulator: 2x Silicon Labs Si2168-B40
Tuner: 2x Silicon Labs Si2157-A30
This patch adds support only for the first tuner.
The demodulator needs firmware, available for example here:
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/
The demodulators sit on the same I2C bus and their addresses
are 0x64 and 0x67. The tuners are behind the demodulators and
their addresses are 0x60 and 0x63.

au0828_v4l2_device_register() unlocks au0828_dev->lock and frees au0828
dev in error legs before return. au0828_usb_probe() does the same when
au0828_v4l2_device_register() returns error.

c8sectpfe driver relied on CONFIG_FW_LOADER_USER_HELPER_FALLBACK option
for loading its xp70 firmware. A previous commit removed this Kconfig
option, as it is apparently harmful, but did not update the driver
code which relied on it.
This patch reworks the firmware loading into the start_feed callback.
At this point we can be sure the rootfs is present, thereby removing
the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.

For the rest, media_device_ioctl() will do the right thing,

A couple of data structures in the dibusb-common file are only
accessed when CONFIG_DVB_DIB3000MC is enabled, otherwise we
get a harmless gcc warning:
usb/dvb-usb/dibusb-common.c:223:34: error: 'dib3000p_panasonic_agc_config' defined but not used
usb/dvb-usb/dibusb-common.c:211:32: error: 'stk3000p_dib3000p_config' defined but not used
This moves the existing #ifdef a few lines up to correctly cover
all the conditional data structures, which gets rid of the warning.

struct ir_raw_event currently has a size of 12 bytes on most (all?)
architectures. This can be reduced to 8 bytes whilst maintaining
full backwards compatibility.
This saves 2KB in size of struct ir_raw_event_ctrl (as element
kfifo is reduced by 512 * 4 bytes) and it allows to copy the
full struct ir_raw_event with a single 64 bit operation.
Successfully tested with the Nuvoton driver and successfully
compile-tested with the ene_ir driver (as it uses the carrier /
duty_cycle elements).

2008-02-25 Andre Weidemann added support for TT S2-3600 and noted
that he still gets image distortions every now and then.
It seems to be common knowledge in many projects that changing
the USB parameters seems to help. OpenELEC has included this patch
for a few years, for example. Nobody bothered to report the issue
upstream though, it seems.

It's been reported that CJC7113 devices are returning

"1111111111111111" found @ 0x4a (stk1160)

add a quirk to allow its autodetection. Given there isn't
any known differences with SAA7113, this commit does not
introduces a new saa711x_model value.

- Add a check for the case that both the cropcap and g_selection ops
are NULL. This shouldn't happen, but I feel happier if the code
guards against this.
- If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error
codes from cropcap. Just assume square pixelaspect ratio in that
case. This situation can happen if the bridge driver's cropcap op
calls the corresponding subdev's op. So the cropcap ioctl is set,
but it might return ENOIOCTLCMD anyway. In the past this would
just return an error which is wrong.
- Call cropcap first and let g_selection overwrite the bounds and
defrect. This safeguards against subdev cropcap implementations
that set those rectangles as well. What g_selection returns has
priority over what such cropcap implementations return.
