Subject: serial: omap: drop unnecessary check from remove
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1b42c8b29b1822436e690fd0a7906aaa62099f91;p=linux-beck.git

serial: omap: drop unnecessary check from remove

if platform_get_drvdata() returns NULL, that's
quite a nasty bug on the driver which we want to
catch ASAP. Otherwise, that check is hugely
unneeded.
