Subject: [PATCH] new fix: radeon backlight shutoff flashes momentarily
Date: Sun, 22 Mar 2009 22:10:10 -0700	[thread overview]
Message-ID: <49C719B2.8070701@earthlink.net> (raw)

This patch should replace the previous
fix-radeon-backlight-shutoff-flashes-momentarily.patch added to -mm tree

This replacement patch removes only the & ~LVDS_BL_MOD_EN on shutoff 
and applies only to machine powerbook5,3 && CHIP_FAMILY_RV350.
