From a3ffcebc87480664aef7c8283394d4cf2aec327c Mon Sep 17 00:00:00 2001 From: Jiapeng Chong Date: Tue, 27 Apr 2021 18:26:34 +0800 Subject: ALSA: usb-audio: Remove redundant assignment to len Variable len is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: sound/usb/mixer.c:2713:3: warning: Value stored to 'len' is never read [clang-analyzer-deadcode.DeadStores].
