Good point. Will send a V2.

Why not keep this one and drop the first one?  Maybe it would be nice to
keep all the initializations related to pix together?

[PATCH] [media] bdisp: remove redundant assignment to pix

[Colin King]

From: Colin Ian King 

Pointer pix is being initialized to a value and a little later
being assigned the same value again. Remove the redundant second
duplicate assignment. Cleans up the clang warning:

drivers/media/platform/sti/bdisp/bdisp-v4l2.c:726:26: warning: Value
stored to 'pix' during its initialization is never read
