From 7ed310bd51bec0b440a551fc4da1993c7f6cd231 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 22 Feb 2018 16:02:22 -0300 Subject: ASoC: soc-generic-dmaengine-pcm: Fix sparse warnings Currently the following sparse warnings are observed: sound/soc/soc-generic-dmaengine-pcm.c:185:34: warning: restricted snd_pcm_format_t degrades to integer sound/soc/soc-generic-dmaengine-pcm.c:186:66: warning: incorrect type in argument 1 (different base types) sound/soc/soc-generic-dmaengine-pcm.c:186:66: expected restricted snd_pcm_format_t [usertype] format sound/soc/soc-generic-dmaengine-pcm.c:186:66: got int [signed] [assigned] i Fix it by changing the loop variable to be of 'snd_pcm_format_t'. Also introduce a SNDRV_PCM_FORMAT_FIRST label, which corresponds to the first member (index 0) of the snd_pcm_format_t formats.
