Subject: staging: r8192e_pci: Change memcpy to memcmp
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ea9f10f2fd207bb70a730ee3b356f75bc00ff41d;p=deliverable%2Flinux.git

staging: r8192e_pci: Change memcpy to memcmp

Routine rtllib_MlmeDisassociateRequest() has a comparison of memcpy()
with NULL, which makes no sense. Analysis of the code suggests that
memcmp() was intended.
