sprdfb_check_var() has two problems:
|
||
|
|
I) it is not buffering-aware, which all Spreadtrum devices use;
|
||
|
|
II) it checks values that are already in yres_virtual, not those that we
|
||
|
|
are trying to overwrite.
|
||
|
|
Those problems stop X11 and charging-sdl from working properly.
|
||
|
|
X11 error:
|
||
|
|
(EE) FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
|
||
|
|
This patch fixes first problem, however, the correct way is fixing
|
||
|
|
the second one, as this might have less side effects.
