hwmon: (lm90) Fix warnings

With some configuration option combinations, we get the following
warnings:

drivers/hwmon/lm90.c: In function 'lm90_detect':
drivers/hwmon/lm90.c:1114: warning: 'chip_id' may be used uninitialized
in this function

uninitialized in this function
drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used
uninitialized in this function

We can solve these easily by reading the register values first and
checking for errors later. These errors should be very rare, even in
the case of failed detection, so this change has no impact on
performance. And this makes checkpatch.pl happier.

If inet_csk_route_child_sock() returns NULL, we should release socket

Another lock imbalance exists if __inet_inherit_port() returns an error

Guennadi Liakhovetski [Fri, 9 Sep 2011 16:39:20 +0000]
[media] V4L: soc-camera: make (almost) all client drivers re-usable outside of the framework

The most important change in this patch is direct linking to struct
soc_camera_link via the client->dev.platform_data pointer. This makes most
of the soc-camera client drivers also usable outside of the soc-camera
framework. After this change all what is needed for these drivers to
function are inclusions of soc-camera headers for some convenience macros,
suitably configured platform data, which is anyway always required, and
loaded soc-camera core module for library functions. If desired, these
library functions can be made generic in the future and moved to a more
neutral location.

The only two client drivers, that still depend on soc-camera are:

mt9t031: it uses struct video_device for its PM. Since no hardware is
available, alternative methods cannot be tested.

ov6650: it uses struct soc_camera_device to pass its sense data back to
the bridge driver. A generic v4l2-subdevice approach should be developed
to perform this.

video_device is returned. Since subdevice drivers currently have no access
to struct video_device objects, the only way to provide this information to

[media] V4L: videobuf2: update buffer state on VIDIOC_QBUF

V4L2 specification states, that the videobuffer state flags have to be
updated on VIDIOC_QBUF ioctl(). Videobuf2 currently doesn't do that,
which is fixed by this patch.

[media] V4L: add two new ioctl()s for multi-size videobuffer management

A possibility to preallocate and initialise buffers of different sizes
in V4L2 is required for an efficient implementation of a snapshot
mode. This patch adds two new ioctl()s: VIDIOC_CREATE_BUFS and
VIDIOC_PREPARE_BUF and defines respective data structures.

[media] V4L: sh-mobile-ceu-camera: fix mixed CSI2 & parallel camera case

The current sh_mobile_ceu_camera driver can cause an Oops, if a CSI2 and a
parallel camera are registered on the same CEU. Fix it by making CSI2
association with a camera more targeted.

[media] V4L: mt9t112: fix broken cropping and scaling

G_CROP, S_CROP, CROPCAP, G_FMT, and S_FMT functionality in the mt9t112
driver was broken on many occasions. This patch allows consistent
cropping for rectangles also larger than VGA and cleans up multiple
other issues in this area. It still doesn't add support for proper
scaling, using the sensor own scaler, so input window is still
always equal to the output frame.
