__ov965x_set_frame_interval
Cast fi->interval.numerator to u64 in order to avoid a potential integer
overflow. This variable is being used in a context that expects an
expression of type u64.

The ov9650 driver currently only supports legacy platform data probe.
This change adds device tree probing.
There has been an attempt to add device tree support for ov9650 driver
by Hugues Fruchet as a part of the patchset that adds support of OV9655
camera (http://www.spinics.net/lists/linux-media/msg117903.html), but
it wasn't merged into mainline because creating a separate driver for
OV9655 is preferred.
This is very similar to Hugues's patch, but not supporting new device.

Previously, the sensor, with default settings, was outputting SOF without
data. This results in frame sync error on the receiver side.
Now, configure the sensor to output SOF with MIPI data for all frames. This
avoids possible null first frame on the bus.

This patch adds driver for Omnivision's ov2685 sensor.
Though the ov2685 can output yuv data, this driver only
supports the raw bayer format, including the following features:
- output 1600x1200 at 30fps
- test patterns
- manual exposure/gain control
- vblank and hblank
- media controller
- runtime pm

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

This is a fix for commit 329d88da4df9 ("[media] media: i2c: Don't export

The problems described only affect the HD-PVR, so it should not affect
other hardware; also if the module happens to be loaded, the i2c IR
part of the HD-PVR will be enabled anyway.

This code implements the transmitter which is currently implemented
in the staging lirc_zilog driver.
The new code does not need a signal database, iow. the
haup-ir-blaster.bin firmware file is no longer needed, and the driver
does not know anything about the keycodes in that file.
Instead, the new driver can send raw IR, but the hardware is limited
to few different lengths of pulse and spaces, so it is best to use
generated IR rather than recorded IR.

The smatch logic gets confused with the syntax used to check if the

drivers/media/i2c/ov9650.c:895 __g_volatile_ctrl() error: uninitialized symbol 'reg1'.
There's nothing wrong with the original logic, except that
it is a little more harder to review.
So, let's stick with the syntax that won't cause read
issues.

As smatch reported:
drivers/media/i2c/imx274.c:659 imx274_regmap_util_write_table_8() error: uninitialized symbol 'err'.
There is a bug at imx274_regmap_util_write_table_8() with causes
it to randomly return a random error if range_count is zero.
Worse than that, the logic there starts with range_count
equal to zero, and periodically resets it to zero again.
As it is a way more likely that err assumes a non-zero value,
I suspect that the chance of this code to run is very small,
so, it would be worth to review the entire function.
Anyway, clearly it shouldn't be returning error if range_count
is zero. So, let's fix it.
