From: Hans Verkuil Date: Mon, 9 Mar 2015 14:47:48 +0000 (-0300) Subject: [media] vivid-tpg: move the 'extras' drawing to a separate function X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c6ff1c1b5ba0cff72f899e3b3ba0343b5a0e0024;p=linux-beck.git [media] vivid-tpg: move the 'extras' drawing to a separate function This moves the drawing code for the extras (border, square, etc) to a function of its own instead of having this in the main for loop.
