Hi all,

After merging the v4l-dvb tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/media/platform/sti/bdisp/bdisp-debug.c: In function 'bdisp_dbg_perf':
drivers/media/platform/sti/bdisp/bdisp-debug.c:600:50: error: expected ';' before ')' token
min_fps = SECOND / (s32)bdisp->dbg.min_duration);
^
drivers/media/platform/sti/bdisp/bdisp-debug.c:600:50: error: expected statement before ')' token


Caused by commit fdf11845cbc1 "bdisp-debug: don't try to divide by s64":

^

I fixed it up for today.

cheers
