The patch titled
imxfb: correct location of callbacks in suspend and resume
has been removed from the -mm tree. Its filename was
imxfb-correct-location-of-callbacks-in-suspend-and-resume.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: imxfb: correct location of callbacks in suspend and resume
From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
The probe function passes a pointer to a struct fb_info to
platform_set_drvdata(), so don't interpret the return value of
platform_get_drvdata() as a pointer to struct imxfb_info.
The original imxfb_info *fbi backlight_power was NULL but in imxfb_suspend
it was 4 resulting in an oops as imxfb_suspend calls
imxfb_disable_controller(fbi) which in turn has
if (fbi->backlight_power)
fbi->backlight_power(0);
