Subject: [PATCH v3 03/26] PCI: dwc: Use PCI_STD_NUM_BARS
Date: Mon, 16 Sep 2019 23:41:35 +0300 [thread overview]
Message-ID: <20190916204158.6889-4-efremov@linux.com> (raw)
In-Reply-To: <20190916204158.6889-1-efremov@linux.com>
To iterate through all possible BARs, loop conditions refactored to the
*number* of BARs "i < PCI_STD_NUM_BARS", instead of the index of the last
valid BAR "i <= BAR_5". This is more idiomatic C style and allows to avoid
the fencepost error. Array definitions changed to PCI_STD_NUM_BARS where
appropriate.
