Subject: staging: gasket: sysfs: remove unnecessary NULL check on device ptr
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=14d70229777f17fe3c22deb559821038663bae78;p=openwrt%2Fstaging%2Fblogic.git

staging: gasket: sysfs: remove unnecessary NULL check on device ptr

The device pointer passed into get_mapping() will never be NULL; the
check is unnecessary.
