Subject: [PATCH v3] PCI: endpoint: pci-epf-test: Fix NULL ptr assignment to dma_chan_rx
Date: Fri, 27 Dec 2024 08:08:41 -0800 [thread overview]
Message-ID: <20241227160841.92382-1-khalfella@gmail.com> (raw)
In-Reply-To: <20241227135948.ztxxx2u37og3ixxn@thinkpad>
If dma_chan_tx allocation fails, set dma_chan_rx to NULL after it is
freed.
Fixes: 8353813c88ef ("PCI: endpoint: Enable DMA tests for endpoints with DMA capabilities")
