Subject: [PATCH] Input: iqs5xx - initialize an uninitialized variable
Date: Mon, 25 Jan 2021 10:35:00 -0600	[thread overview]
Message-ID: <1611592500-32209-1-git-send-email-jeff@labundy.com> (raw)

If execution jumps to the err_kfree label, error_bl is evaluated
before it is initialized. Fix this by initializing it to zero.

Fixes: 2539da6677b6 ("Input: iqs5xx - preserve bootloader errors")
Reported-by: kernel test robot <lkp@intel.com>
