imxfb: correct location of callbacks in suspend and resume
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); Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Sascha Hauer <kernel@pengutronix.de> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
