From 2dbab9784db1c0de517922d81394d9ff4a33c544 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 7 Oct 2014 15:09:26 +0200 Subject: ASoC: simple-card: Initialize headphone and mic GPIO numbers The uninitialized default of 0 for gpio_hp_det and gpio_mic_det doesn't play well with asm-generic's gpio_is_valid(): static inline bool gpio_is_valid(int number) { return number >= 0 && number < ARCH_NR_GPIOS; } Hence on r8a7740/armadillo-legacy: sh-mobile-hdmi sh-mobile-hdmi: SH Mobile HDMI Audio Codec sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Mic Jack After that the kernel log is spammed ca. 7 times per second with: sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones Initialize the GPIO numbers with a negative number (-ENOENT) to fix this.
