Wrong vsync offset calculation in drm_edid.c

2013-03-07 Thread Peter Blum
This patch is a bug fix for the file drm_edid.c of the kernel 3.8. The vsync offset is calculated wrong from the EDID set because of the wrong shift direction. We could measure the bad old setting and also the good new setting after the bug fix. Signed-off-by: Peter Blum diff -Naur
