Subject: [PATCH 38/41] drivers: tty: serial: xilinx_uartps: fill mapsize and use it
Date: Sat, 27 Apr 2019 14:52:19 +0200 [thread overview]
Message-ID: <1556369542-13247-39-git-send-email-info@metux.net> (raw)
In-Reply-To: <1556369542-13247-1-git-send-email-info@metux.net>
Fill the struct uart_port->mapsize field and use it, insteaf of
hardcoded values in many places. This makes the code layout a bit
more consistent and easily allows using generic helpers for the
io memory handling.
Candidates for such helpers could be eg. the request+ioremap and
iounmap+release combinations.
