Subject: staging: rtl8192u: rewrite NULL comparison for pointers
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b8a99fb513a63397b43f63f4825371f64a79e821;p=linux-beck.git

staging: rtl8192u: rewrite NULL comparison for pointers

When testing pointers, it is not necessary to explicitly compare to
NULL. Rewrite if condition as (!ptr) or (ptr) as suggested in
Documentation/CodingStyle
