[Qemu-devel] [PATCH 1.0] checkpatch.pl: fix CAST detection

[Paolo Bonzini]

From: Florian Mickler <address@hidden>

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);
