From a19c921fca0a865b657d59b2c9a05aa0a2905126 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Fri, 15 Apr 2016 15:28:52 +0200 Subject: ALSA: lx646es: Fix possible uninitialized variable reference lx_pipe_state() checks the return value from lx_message_send_atomic() and breaks the loop only when it's a negative value. However, lx_message_send_atomic() may return a positive error code (as the return code from the hardware), and then lx_pipe_state() tries to compare the uninitialized current_state variable. Fix this behavior by checking the positive non-zero error code as well.
