Subject: serial: altera_uart: call iounmap() at driver remove
X-Git-Tag: MMI-PSA29.97-13-9~5519^2
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59fe2cc8b1c32dd139da80fc8222b5b3290b7a09;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

serial: altera_uart: call iounmap() at driver remove

The driver calls ioremap() in the probe function but doesn't call
iounmap() in the remove function correspondingly. Do so now.

Follow commit 5c9d6abed9e0 ("serial: altera_jtaguart: adding iounmap()")
