From c9e272f9e03d412073a3ae2c1814efbec10b6278 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 18 Jun 2020 13:08:42 +0200 Subject: [PATCH] ALSA: hda: Let LED cdev handling suspend/resume Set LED_CORE_SUSPENDRESUME to LED cdev flags, so that the LED core would store and restore the LED status at suspend/resume. In theory, the codec driver should be responsible for all LED bits, but this might be safer and cover the overlooked cases.
