4c62e9764a Drivers: media: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

9c016d6109 Partly revert "[media] uvcvideo: Set error_idx properly for extended controls API failures"
Commit f0ed2ce840 ("[media] uvcvideo: Set error_idx properly for
extended controls API failures") causes user space to behave incorrectly
on one of my test machines (there is no sound under KDE 4.9.4 using
pulseaudio and there is a knotify4 process occupying one of the CPU
cores 100% of the time).  Reverting that commit entirely fixes the
problem for me.

However, commit f0ed2ce840 appears to do more than it follows from its
changelog, because the changelog only says about the changes related to
ctrls->error_idx, while the commit additionally changes error codes
returned by various functions in uvc_ctrl.c and uvc_v4l2.c.  It turns
out that the changes of the returned error codes confuse the user spce,
so it is sufficient to revert the part of commit f0ed2ce840 not
mentioned in its changelog to fix the problem.

[ 'ENOENT' is not a valid error return from an ioctl to begin with, and
  I don't understand how anybody ever even thought it would be.  - Linus ]

64ae9958a6 [media] uvcvideo: Fix control value clamping for unsigned integer controls
V4L2 integer controls are stored in signed 32-bit values. However, UVC
controls can be either signed or unsigned. Take the UVC control
signedness into account when clamping the control value to the min-max
range.

8be8ec6ea5 [media] uvcvideo: Mark first output terminal as default video node
The MEDIA_ENT_FL_DEFAULT identifies entities that are considered as
default for their group and type. For video nodes, it identifies the
node that application should use by default.
UVC devices don't report which output terminal should be considered as
the default, use the first one. Most devices have a single output
terminal anyway.

With registers 0x01 and 0x03, a fine grained adjustment with

41269386b0 [media] dvb_usb_v2: switch interruptible mutex to normal
Fixes error: dvb_usb_v2: pid_filter() failed=-4

error code -4 is EINTR, Interrupted system call

That error blocks I/O in some cases as -EINTR error was returned
by the mutex which was protecting USB control messages. We want
configure hardware to sleep mode on every case after tuning is
stopped. That kind of behavior blocks it, leaving hardware some
unwanted state in worst case.

That error was seen every time when af9015 was plugged to USB1.1
which leads use of hardware PID filters. Stop tuning (tzap) with
ctrl+c failed as driver tries to remove hardware PID filters.

Tested with every hardware which uses routine in question.

ede4c3a5a6 [media] gscpa: get rid of warning: suggest braces around empty body
There are hundreds of messages like this one, when GSPCA debug is
disabled, when compiled with W=1:
drivers/media/usb/gspca/spca500.c:725:46: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
Get rid of it, especially as it might actually cause troubles on
some places.

eda94710d6 [media] pwc-if: must check vb2_queue_init() success
drivers/media/usb/pwc/pwc-if.c: In function 'usb_pwc_probe':
drivers/media/usb/pwc/pwc-if.c:1003:16: warning: ignoring return value of 'vb2_queue_init', declared with attribute warn_unused_result [-Wunused-result]
In the past, it used to have a logic there at queue init that would
BUG() on errors. This logic got removed. Drivers are now required
to explicitly handle the queue initialization errors, or very bad
things may happen.
