The patch titled drivers/video/backlight/aat2870_bl.c: fix setting max_current has been removed from the -mm tree. Its filename was drivers-video-backlight-aat2870_blc-fix-setting-max_current.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: drivers/video/backlight/aat2870_bl.c: fix setting max_current From: Axel Lin <axel.lin@xxxxxxxxx> - Current implementation tests wrong value for setting aat2870_bl->max_current. - In the current implementation, we cannot differentiate between 2 cases: a) if pdata->max_current is not set , or b) pdata->max_current is set to AAT2870_CURRENT_0_45 (which is also 0). Fix it by setting AAT2870_CURRENT_0_45 to be 1 and adjust the equation in aat2870_brightness() accordingly.
