From 74c34ca1cc12884703c70d34ed333517d978c2e7 Mon Sep 17 00:00:00 2001 From: Eldad Zack Date: Tue, 23 Apr 2013 01:00:41 +0200 Subject: ALSA: pcm_format_to_bits strong-typed conversion Add a function to handle conversion from snd_pcm_format_t to bitwise with proper typing. Change such conversions to use this function and silence sparse warnings.
