Subject: checkpatch.pl: fix CAST detection
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c023e4734c3e8801e0ecb5e81b831d42a374d861;p=openwrt%2Fstaging%2Fblogic.git

checkpatch.pl: fix CAST detection

We should only claim that something is a cast if we did not encouter a
token before, that did set av_pending.

This fixes the operator * in the line below to be detected as binary (vs
unary).

kmalloc(sizeof(struct alphatrack_ocmd) * true_size, GFP_KERNEL);
