From 8121d91c02a1be4884821599472acf405efdc3de Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 7 Feb 2011 20:25:19 +0300 Subject: [PATCH] ALSA: USB: 6fire: signedness bug in usb6fire_pcm_prepare() rt->rate is an unsigned char so it's never equal to -1. It's not a huge problem because the invalid rate is caught inside the call to usb6fire_pcm_set_rate() which returns -EINVAL. But if we fix the test then it prints out the correct error message so that's good.
