77639ff2b3 [media] adv7604: fix inverted condition
The log_status function should show HDMI information, but the test checking for
an HDMI input was inverted. Fix this.

58e43d90b9 [media] smiapp: Fix power count handling
The sensor may be powered by either one of its sub-devices being accessed
from the user space (an open file handle) or by its s_power() op being
called with non-zero on argument. The driver counts the users and if any
reason to keep the device powered exists it will be powered.

However, a faulty condition was used in recognising the need to power off
the sensor, leading it to be powered off every time any of its uses went
away.

c5540fbb9d [media] rc-core: remove protocol arrays
The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

120703f9eb [media] rc-core: document the protocol type
Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

0d5e8c4313 [media] Fix 64-bit division fall-out from 64-bit control ranges
Commit 0ba2aeb6da increased the internal control ranges
to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
control values in a division or modulus operations since not all architectures support
those natively.

Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

2a9ec37311 [media] v4l2-ctrls: use ptrs for all but the s32 type
Rather than having two unions for all types just keep 'val' and
'cur.val' and use the p_cur and p_new unions to access all others.

The only reason for keeping 'val' and 'cur.val' is that it is used
all over, so converting this as well would be a huge job.

0ba2aeb6da [media] v4l2-ctrls: increase internal min/max/step/def to 64 bit
While VIDIOC_QUERYCTRL is limited to 32 bit min/max/step/def values
for controls, the upcoming VIDIOC_QUERY_EXT_CTRL isn't. So increase
the internal representation to 64 bits in preparation.

Because of these changes the msi3101 driver has been modified slightly
to fix a formatting issue (%d becomes %lld), vivi had to be modified
as well to cope with the new 64-bit min/max values and the PIXEL_RATE
control in a few sensor drivers required proper min/max/def values.

16-bit registers are read through two 8-bit read operations. Factorize
that common pattern into 16-bit read accessors to simplify the code.

The subdev EDID ioctls receive a pad field that must reference an
existing pad and an EDID field that must point to a buffer. Validate
both fields in the core code instead of duplicating validation in all
drivers.
