power: fix sysfs_read/sysfs_write usage
* The incoming path to sysfs_read/sysfs_write should be const, as in open(2) call. * Redefine scaling_gov_path as const pointer array. * Since sysfs_read works on a simple absolute path anyway, make sure the scaling_gov_path paths *are* absolute. Otherwise the code only works if Power HAL has / as CWD, which is a bit fragile. Change-Id: I70c08f8137842569514bcb3f6e0617d46044e6ab Signed-off-by: Corinna Vinschen <xda@vinschen.de>
