[PATCH -next] drm/amdgpu/sdma: add missing release_firmware() in amdgpu_sdma_init_microcode()

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

 



In some error path in amdgpu_sdma_init_microcode(), release_firmware() is
not called, the memory allocated in request_firmware() will be leaked,
calling amdgpu_sdma_destroy_inst_ctx() which calls release_firmware() to
avoid memory leak.
