From 25c8888ad65f812c847ae58398a5f8f1b20b0a95 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 12 Jun 2015 17:19:15 +0800 Subject: [PATCH] ASoC: rt5645: Use devm_gpiod_get_optional for hp-detect Since hp-detect is optional, use devm_gpiod_get_optional instead. In additional, it should return error if devm_gpiod_get_optional fails.
