Subject: [PATCH] ALSA: control: remove useless assignment in .info callback of PCM chmap element
Git-commit: 1faa9d3a3ea7852761ff403f5a9d4a409c0bb199
Patch-mainline: v5.6-rc1
References: git-fixes

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.
