Subject: [PATCH] Bluetooth: hci_qca: resolve various warnings
Message-ID: <20201101025215.GA4828@fedora-project>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

Use template string as opposed to function name. Add a blank
line after declaration to improve readability. Replace symbolic
permissions with octal values. Use usleep_range for small msec
values due to the fact that msleep() less than 20ms may have
unexpected behavior/sleep longer. This patch removes all
checkpatch warnings.
