Subject: [PATCH] media: st-delta: Remove redundant assignment to ret

Variable ret is being assigned a value however the assignment is
never read, so this redundant assignment can be removed.

Clean up the following clang-analyzer warning:

drivers/media/platform/sti/delta/delta-v4l2.c:1010:4: warning: Value
stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores].
