Subject: media: s2255drv: Remove unneeded if else blocks
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d2d476b705b4930427d2efc38cfe0ea0c5d1cb4c;p=openwrt%2Fstaging%2Fblogic.git

media: s2255drv: Remove unneeded if else blocks

Given the following definitions from s2255drv.c

 #define LINE_SZ_4CIFS_NTSC      640
 #define LINE_SZ_2CIFS_NTSC      640
 #define LINE_SZ_1CIFS_NTSC      320

and

 #define LINE_SZ_4CIFS_PAL       704
 #define LINE_SZ_2CIFS_PAL       704
 #define LINE_SZ_1CIFS_PAL       352

f->fmt.pix.width possible values can be reduced to
LINE_SZ_4CIFS_NTSC or LINE_SZ_1CIFS_NTSC.

This patch removes unneeded if else blocks in vidioc_try_fmt_vid_cap
function.

This issue was detected by using the Coccinelle software.
