X-Git-Tag: firefly_0821_release~3680^2~4337^2~3 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d98b15db376b9cc35f74fd2bd432b9fc287a5999;p=firefly-linux-kernel-4.4.55.git xen/xenbus: Remove the unnecessary check. .. we check whether 'xdev' is NULL - but there is no need for it as the 'dev' check is done before. The 'dev' is embedded in the 'xdev' so having xdev != NULL with dev being being checked is not going to happen.
