Peter Senna Tschudin 7b34be71db [media] use IS_ENABLED() macro
This patch introduces the use of IS_ENABLED() macro. For example,
replacing:
 #if defined(CONFIG_I2C) || (defined(CONFIG_I2C_MODULE) && defined(MODULE))
with:
 #if IS_ENABLED(CONFIG_I2C)
All changes made by this patch respect the same replacement pattern.

Nickolai Zeldovich bb71b14d80 [media] drivers/media/pci: use memmove for overlapping regions
Change several memcpy() to memmove() in cases when the regions are
definitely overlapping; memcpy() of overlapping regions is undefined

The idx values passed to cx18_i2c_register() and ivtv_i2c_register()
by cx18_init_subdevs() and ivtv_load_and_init_modules() respectively
are always in-range, based on how the hw_all bitmask is populated.
Previously, the checks were already ineffective because arrays were
being dereferenced using the index before the check.

Hans Verkuil ed986d1fee [media] meye: convert to the control framework
Convert the meye driver to the control framework. Some private controls
have been replaced with standardized controls (SHARPNESS and JPEGQUAL).
The AGC control looks like it can be replaced by the AUTOGAIN control, but
it isn't a boolean so I do not know how to interpret it.
The FRAMERATE control looks like it can be replaced by S_PARM, but again,
without knowing how to interpret it I decided to leave it alone.

Mauro Carvalho Chehab 2c46bb119f [media] ngene: fix commit 36a495a336
The above commit were applied only partially; it broke tuner and
demod attach, but the part that added it to ngene_info was missing.

Not sure what happened there, but, without this patch, a regression
would be happening.

Also, gcc complains about a defined but not used symbol.

So, apply manually the missing part.

Greg Kroah-Hartman 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.

Simon Farnsworth 8773986894 [media] saa7134: Add pm_qos_request to fix video corruption
The SAA7134 appears to have trouble buffering more than one line of video
when doing DMA. Rather than try to fix the driver to cope (as has been done
by Andy Walls for the cx18 driver), put in a pm_qos_request to limit deep
sleep exit latencies.
The visible effect of not having this is that seemingly random lines are
only partly transferred - if you feed in a static image, you see a portion
of the image "flicker" into place.

Nikolaus Schulz 30ad64b8ac [media] dvb: push down ioctl lock in dvb_usercopy
Since most dvb ioctls wrap their real work with dvb_usercopy, the static mutex
used in dvb_usercopy effectively is a global lock for dvb ioctls.
Unfortunately, frontend ioctls can be blocked by the frontend thread for
several seconds; this leads to unacceptable lock contention.  Mitigate that by
pushing the mutex from dvb_usercopy down to the individual, device specific
ioctls.
There are 10 such ioctl functions using dvb_usercopy, either calling it
directly, or via the trivial wrapper dvb_generic_ioctl. The following already
employ their own locking and look safe:
    • dvb_demux_ioctl           (as per dvb_demux_do_ioctl)
    • dvb_dvr_ioctl             (as per dvb_dvr_do_ioctl)
    • dvb_osd_ioctl             (as per single non-trivial callee)
    • fdtv_ca_ioctl             (as per callees)
    • dvb_frontend_ioctl
The following functions do not, and are thus changed to use a device specific
mutex:
    • dvb_net_ioctl             (as per dvb_net_do_ioctl)
    • dvb_ca_en50221_io_ioctl   (as per dvb_ca_en50221_io_do_ioctl)
    • dvb_video_ioctl
    • dvb_audio_ioctl
    • dvb_ca_ioctl

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

While here, replace strlen()+kmemdup() to kstrdup().

Note: there is already a mantis_exit at the mantis driver. So,
this should be renamed to mantis_input_exit.

The mantis_input code is currently unused, as it doesn't implement the RC API
right.

Patches for it are sent for discussions, but were never
accepted. So, while this is not fixed, the entire code inside
mantis_input can simply be commented.
