[PATCH] drm: tegra: fix memory leak in error handling path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Lv Ruyi <lv.ruyi@xxxxxxxxxx>

Before leave the nvdec_load_firmware, we shuold free virt which is alloced
by dma_alloc_coherent, so change "return err" to "goto cleanup".
