[PATCH RFC] staging: media: davinci_vpfe: drop condition with no effect

[Nicholas Mc Guire]

As the if and else branch body are identical the condition has no effect and 
can be dropped.

As the if and the else branch of the inner conditional paths are the same
the condition is without effect. Given the comments indicate that
the else branch *should* be handling a specific case this may indicate
a bug, in which case the below patch is *wrong*. This needs a review by
someone that knows the specifics of this driver.

If the inner if/else is a placeholder for planed updates then it should
be commented so this is clear.

Patch was only compile tested with davinci_all_defconfig + CONFIG_STAGING=y
CONFIG_STAGING_MEDIA=y, CONFIG_MEDIA_SUPPORT=m,
CONFIG_MEDIA_ANALOG_TV_SUPPORT=y, CONFIG_MEDIA_CAMERA_SUPPORT=y
CONFIG_MEDIA_CONTROLLER=y, CONFIG_VIDEO_V4L2_SUBDEV_API=y
CONFIG_VIDEO_DM365_VPFE=m

Patch is against 3.0.19-rc5 -next-20150123
