3.5.7.15 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Hung <[email protected]> commit 4ef366c583d6180b1c951147869ee5a3038834f2 upstream. On HP 1000 lapops, BIOS reports minimum backlight on boot and causes backlight to dim completely. This ignores the initial backlight values and set to max brightness.
