Subject: [PATCH 0/8] Fixes and updates when using AUX backlight using Luminance
Date: Fri, 20 Feb 2026 10:32:09 +0530	[thread overview]
Message-ID: <20260220050217.2453681-1-suraj.kandpal@intel.com> (raw)

This series aims to fix/update some code with respect to AUX backlight
via luminance values for both VESA and INTEL HDR codepaths.
The below are the major changes made in this series.
- Do not allow 0 brightness  by default which makes the screen go blank
leaving user with no way to see the screen and increase brightness.
- Take into account luminance_set variable when we decide which funcs
need to be enabled
- Update debug logs to make them more concise and help debug which
code path was taken
