From: Takashi Sakamoto Date: Thu, 9 Apr 2015 23:43:00 +0000 (+0900) Subject: ALSA: ctl: evaluate macro instead of numerical value X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=39d118677baa;p=linux-beck.git ALSA: ctl: evaluate macro instead of numerical value SNDRV_CTL_TLV_OP_XXX is defined but not used in core code. Instead, raw numerical value is evaluated. This commit replaces these values to these macros for better looking.
