Subject: [PATCH 14/54] 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
|
|
