Subject: media: ti: davinci: vpbe_display.c: return 0 instead of 'ret'.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0d3732fb1b20d2a636d294cdf51c35f9233d622a;p=linux.git

media: ti: davinci: vpbe_display.c: return 0 instead of 'ret'.

Since 'ret' is known to be 0, just return '0'. This fixes a smatch warning:

vpbe_display.c:1152 vpbe_display_open() warn: missing error code? 'err'
