media: Remove redundant pm_runtime_mark_last_busy() calls

2025-08-18T07:55:08+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

media: rkvdec: Fix an error handling path in rkvdec_probe()

2025-08-18T07:55:05+00:00

If an error occurs after a successful iommu_paging_domain_alloc() call, it should be undone by a corresponding iommu_domain_free() call, as already done in the remove function. In order to fix the issue, move the corresponding call at the end of the function, because it is safe to allocate 'empty_domain' later.

2025-08-18T07:55:04+00:00

The iommu_paging_domain_alloc() function doesn't return NULL on error it returns error pointers. Update the check and then set ->empty_domain to NULL because the rest of the driver assumes it can be NULL.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

The venus driver fails to check if dev_pm_opp_find_freq_{ceil,floor}() returns an error pointer before calling dev_pm_opp_put(). This causes a crash when OPP tables are not present in device tree.

media: amphion: Support dmabuf and v4l2 buffer without binding

2025-07-12T06:34:48+00:00

When using VB2_DMABUF, the relationship between dma-buf and v4l2 buffer may not one-to-one, a single dma-buf may be queued via different v4l2 buffers, and different dma-bufs may be queued via the same v4l2 buffer, so it's not appropriate to use the v4l2 buffer index as the frame store id. We can generate a frame store id according to the dma address. Then for a given dma-buf, the id is fixed. Driver now manages the frame store and vb2-buffer states independently. When a dmabuf is queued via another v4l2 buffer before the buffer is released by firmware, need to pend it until firmware release it.
