Subject: dmatest: prevent memory leakage on error path in thread
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8e1f50d7433b9a6e52cb296943f53c3ce8189ea5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

dmatest: prevent memory leakage on error path in thread

When we fail to allocate memory for thread->srcs or thread->dsts and src_cnt or
dst_cnt great than 1 we leak memory on error path. This patch fixes the issue.
