Markus Elfring 837fdcf05a [media] DaVinci-VPBE: Reduce the scope for a variable in vpbe_set_default_output()
* Move the definition for the variable "ret" into an if branch
  so that an extra initialisation can be avoided at the beginning
  by this refactoring.

* Return a success code as a constant at the end.

Arnd Bergmann ff681022c6 [media] platform: pxa_camera: add VIDEO_V4L2 dependency
Moving the pxa_camera driver from soc_camera lots the implied
VIDEO_V4L2 Kconfig dependency, and building the driver without

Mauro Carvalho Chehab 759a4ed4d8 [media] platform: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.

As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.

So, join those continuation lines.

The patch was generated via the script below, and manually
adjusted if needed.

Instead of relying on the "simple-bus" compatible and the driver core
populating FIMC-IS child devices make the fimc-is driver populating
its child devices.  This prevents issues related to accessing ISP_I2C
clock registers with corresponding power domain switched off, which
popped out after applying some pending IOMMU driver patches.  Now the
I2C_ISP child devices will be instantiated only when required parent
device drivers are initialized and ready.
