Subject: [PATCH 4/4] firmware: Ignore abort check when no user-helper is used
Date: Tue, 29 Jan 2013 15:46:54 +0100 [thread overview]
Message-ID: <1359470814-7993-5-git-send-email-tiwai@suse.de> (raw)
In-Reply-To: <1359470814-7993-1-git-send-email-tiwai@suse.de>
FW_STATUS_ABORT can be set only during the user-helper invocation,
thus we can ignore the check when CONFIG_HW_LOADER_USER_HELPER is
disabled.
