Subject: media: ti-vpe: cal: Use a loop to create CAMERARX and context instances
X-Git-Tag: v5.10.7~1904^2~133
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2f63379b93fa389ed65432d456da6697f60f7338;p=platform%2Fkernel%2Flinux-rpi.git

media: ti-vpe: cal: Use a loop to create CAMERARX and context instances

Replace a manually unrolled loop with an explicit for loop to increase
readability when creating the CAMERARX and context instances. The
explicit NULL initialization of cal->phy[] and cal->ctx[] is removed, as
the cal structure is zeroed when allocated.
