From 1faa9d3a3ea7852761ff403f5a9d4a409c0bb199 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Sat, 14 Dec 2019 22:13:51 +0900 Subject: [PATCH] ALSA: control: remove useless assignment in .info callback of PCM chmap element Control elements for PCM chmap return information to userspace abount the maximum number of available PCM channels as the number of values in the element. In current implementation the number is once initialized to zero, then assigned to. This is useless and this commit fixes it.
