commit: b8c4321f3d194469007f5f5f2b34ec278c264a04 From: Alexander Holler <[email protected]> Date: Tue, 14 Aug 2012 09:11:09 +0200 Subject: video/udlfb: fix line counting in fb_write
Line 0 and 1 were both written to line 0 (on the display) and all subsequent lines had an offset of -1. The result was that the last line on the display was never overwritten by writes to /dev/fbN.
