ef2d41b19b [media] davinci: remove VPBE_ENC_DV_PRESET and rename VPBE_ENC_CUSTOM_TIMINGS
Remove VPBE_ENC_DV_PRESET (the DV_PRESET API is no longer supported) and
VPBE_ENC_CUSTOM_TIMINGS is renamed to VPBE_ENC_DV_TIMINGS since the old
"CUSTOM_TIMINGS" name is deprecated in favor of "DV_TIMINGS".

Finally remove the dv_preset support from this driver. Note that dv_preset
support was already removed from any bridge drivers that use this i2c
driver, so the dv_preset ops were no longer called and can be removed

In the functions tvp7002_mbus_fmt(), tvp7002_log_status and tvp7002_probe()

* Drop the corresponding rdy_queue, since a subsequent STREAMON expects

code:

				      GFP_KERNEL);
	if (!dev->_audiofilename) {
		err = -ENOMEM;

7f6301d125 [media] em28xx-i2c: relax error check in em28xx_i2c_recv_bytes()
It turned out that some devices return less bytes then requested via i2c when
ALL of the following 3 conditions are met:
- i2c bus B is used
- there was no attempt to write to the specified slave address before
- no device present at the specified slave address
With the current code, this triggers an -EIO error and prints a message to the
system log.
Because it can happen very often during device probing, it is better to ignore
this error and bail out silently after the follwing i2c transaction success
check with -ENODEV.

b78a1f3722 [media] m920x: let GCC see 'ret' is used initialized
Since commit 7543f344e9 ("[media] m920x:
factor out a m920x_write_seq() function") building m920x.o triggers this
GCC warning:
    drivers/media/usb/dvb-usb/m920x.c: In function ‘m920x_probe’:
    drivers/media/usb/dvb-usb/m920x.c:91:6: warning: ‘ret’ may be used uninitialized in this function [-Wuninitialized]
This warning is caused by m920x_write_seq(), which is apparently inlined
into m920x_probe(). It is clear why GCC thinks 'ret' may be used
uninitialized. But in practice the first seq->address will always be
non-zero when this function is called. That means we can change the
while()-do{} loop into a do{}-while() loop. And that suffices to make
GCC see that 'ret' will not be used uninitialized.

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on

platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.
Similarly probe() methods should not be marked __init unless
platform_driver_probe() is used.
