3.5.7.15 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Hung <[email protected]> commit fedbe9bc6fd3e14b1ffbb3dac407777ac4a3650c upstream. On HP m4 lapops, BIOS reports minimum backlight on boot and causes backlight to dim completely. This ignores the initial backlight values and set to max brightness.
