Subject: [PATCH] video: fbdev: use msecs_to_jiffies for time conversion

This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).

Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>

Patch was only compile tested with viper_defconfig (implies CONFIG_FB_PXA=m)

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
