The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Exiting early in remove without releasing all acquired resources yields leaks. Note that e.g. memory allocated with devm_zalloc() is freed after .remove() returns, even if the return code was negative. While blocking_notifier_chain_unregister() won't fail and so the change is somewhat cosmetic, platform driver's .remove callbacks are about to be converted to return void. To prepare that, keep the error message but don't return early. Signed-off-by:

In rkvdec_probe, rkvdec->watchdog_work is bound with rkvdec_watchdog_func. Then rkvdec_vp9_run may be called to start the work. If we remove the module which will call rkvdec_remove to make cleanup, there may be a unfinished work. The possible sequence is as follows, which will cause a typical UAF bug. Fix it by canceling the work before cleanup in rkvdec_remove.

While the decoder can produce frames in both MM21 and MT21C formats, only MM21 is currently supported by userspace tools (like gstreamer and libyuv). In order to ensure userspace keeps working after the SCP firmware is updated to support both MM21 and MT21C formats, force the MM21 format for the capture queue. This is meant as a stopgap solution while dynamic format switching between MM21 and MT21C isn't implemented in the driver.

Given that only the MM21 capture format is supported by userspace tools (like gstreamer and libyuv), make it the default capture format. This allows us to force the MM21 format even when a MM21 and MT21C capable firmware is available (which is needed while dynamic format switching isn't implemented in the driver), without causing the following regressions on v4l2-compliance: fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_G_FMT: FAIL fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_TRY_FMT: FAIL fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_S_FMT: FAIL Fixes: 7501edef ("media: mediatek: vcodec: Different codec using different capture format") Signed-off-by: -

Because the decoder nodes already make use of the iommus property to configure the IOMMU for address translations, having a dma-ranges property makes no sense. In fact, after commit f1ad5338 ("of: Fix "dma-ranges" handling for bus controllers"), having a dma-ranges property causes IOMMU faults. Remove the dma-ranges property and update the example.
