[patch 2/2] ps3fb: Fix spurious mode change failures
From: Geert Uytterhoeven <hidden>
Date: 2007-08-31 13:49:13
From: Geert Uytterhoeven <redacted> ps3fb: Add a `mode' parameter to ps3fb_get_res_table(), as in some cases it should check the full-screen flag of the _new_ video mode instead of the current video mode. This bug caused spurious mode change failures when switching between fullscreen and non-fullscreen modes using fbset, while ps3-video-mode worked fine.
