Subject: [PATCH] usb: misc: ehset: fix wrong if condition
Date: Wed, 5 Jul 2023 17:52:31 +0800 [thread overview]
Message-ID: <20230705095231.457860-1-xu.yang_2@nxp.com> (raw)
A negative number from ret means the host controller had failed to send
usb message and 0 means succeed. Therefore, the if logic is wrong here
and this patch will fix it.
Fixes: f2b42379c576 ("usb: misc: ehset: Rework test mode entry")
