Subject: [PATCH v2 05/10] xhci: dbc: Check for errors first in xhci_dbc_stop()
Date: Mon, 16 Oct 2023 16:09:29 +0300 [thread overview]
Message-ID: <20231016130934.1158504-6-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20231016130934.1158504-1-andriy.shevchenko@linux.intel.com>
The usual patter is to check for errors and then continue if none.
Apply that pattern to xhci_dbc_stop() code.
