Hi all, After merging the sound-asoc tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: sound/soc/codecs/rt5645.c: In function 'rt5645_set_jack_detect': sound/soc/codecs/rt5645.c:2555:2: error: implicit declaration of function 'rt5645_irq_detection' [-Werror=implicit-function-declaration] rt5645_irq_detection(rt5645); ^ sound/soc/codecs/rt5645.c: At top level: sound/soc/codecs/rt5645.c:2591:12: error: static declaration of 'rt5645_irq_detection' follows non-static declaration static int rt5645_irq_detection(struct rt5645_priv *rt5645) ^ sound/soc/codecs/rt5645.c:2555:2: note: previous implicit declaration of 'rt5645_irq_detection' was here rt5645_irq_detection(rt5645); ^ sound/soc/codecs/rt5645.c:2591:12: warning: 'rt5645_irq_detection' defined but not used [-Wunused-function] static int rt5645_irq_detection(struct rt5645_priv *rt5645) ^ Caused by commit 6e747d5311fc ("ASoC: rt5645: Adds push button support for rt5650"). I have used the sound-asoc tree from next-20150429 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
