Subject: drm/i915/backlight: switch to kernel unsigned int types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: fd620bf92a609315241fa5440d336ef17ea76550
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

We have fairly mixed uintN_t vs. uN usage throughout the driver, but try
to stick to kernel types at least where it's more prevalent.
