Subject: [PATCH v3 20/26] staging: gasket: Use PCI_STD_NUM_BARS
Date: Mon, 16 Sep 2019 23:41:52 +0300 [thread overview]
Message-ID: <20190916204158.6889-21-efremov@linux.com> (raw)
In-Reply-To: <20190916204158.6889-1-efremov@linux.com>
Remove local definition GASKET_NUM_BARS for the number of PCI BARs and use
global one PCI_STD_NUM_BARS instead.
