Subject: staging: dgap: remove unnecessary if statement for checking NULL
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9f2b744475b141a2d8e1bf047ecd06a054f300e3;p=openwrt%2Fstaging%2Fblogic.git

staging: dgap: remove unnecessary if statement for checking NULL

dgap_release_remap() function is only called after the memory
has been remapped so if statement for checking NULL doesn't
need.

And also release_mem_region() calls are moved after iounmap() calls.
