From 81cb324675eec592ab8f3038f980c074fbf7fb9b Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 11 Sep 2012 14:12:43 +0300 Subject: [PATCH] ALSA: compress_core: fix open flags test in snd_compr_open() O_RDONLY is zero so the original test (f->f_flags & O_RDONLY) is always false and it will never do compress capture. The test for O_WRONLY is also slightly off. The original test would consider "->flags = (O_WRONLY | O_RDWR)" as write only instead of rejecting it as invalid. I've also removed the pr_err() because that could flood dmesg.
