Subject: NFC: Remove unneeded pn533 dev NULL check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0f909361062d42b0ff7c6522e2347b56a0bf43cc;p=openwrt%2Fstaging%2Fblogic.git

NFC: Remove unneeded pn533 dev NULL check

container_of() works by subtracting the offset of the member.  The math
can't really return a zero here.  Sometimes people check it when they
actually meant to check something else but in this case we can just
remove the check.
