Subject: [PATCH] rt2800usb: check Autorun mode on FW load only once
Date: Thu, 19 Mar 2015 15:32:49 +0100	[thread overview]
Message-ID: <20150319143249.GB2516@redhat.com> (raw)
In-Reply-To: <550ACDF2.30507@linutronix.de>

Seems H/W report correctly firmware Autorun value only at initialization
stage. When we close interface and open it again, Autorun value is 0 and
we try to load firmware what kills the device. To fix clear
REQUIRE_FIRMWARE firmware flag, to do not load firmware again, once we
discover Autorun mode.
