Subject: [PATCH 14/56] Fix brightness range not being complete on Samsung
devices
On some devices, minimum brightness is 0, which totally messes with
Brightness computations (minimum float brightness becomes -1.0 instead
of 0.0...).
Cheat and have them report 1 as minimum instead, which fixes the slope
