If NO_DMA=y: drivers/built-in.o: In function `vb2_vmalloc_dmabuf_ops_detach': videobuf2-vmalloc.c:(.text+0x6f11b0): undefined reference to `dma_unmap_sg' drivers/built-in.o: In function `vb2_vmalloc_dmabuf_ops_map': videobuf2-vmalloc.c:(.text+0x6f1266): undefined reference to `dma_unmap_sg' videobuf2-vmalloc.c:(.text+0x6f1282): undefined reference to `dma_map_sg' As we don't want to make the core VIDEOBUF2_VMALLOC depend on HAS_DMA (it's v4l2 core code, and selected by a lot of drivers), stub out the DMA support if HAS_DMA is not set.

Since commit da6e162d ("[media] rc-core: simplify sysfs code"), when the IR protocol is set using the sysfs interface to the same set of protocols that are already set, store_protocols() does not refresh the scancode filter with the new protocol, even if it has already called the change_protocol() callback successfully. This results in the filter being disabled in the hardware and not re-enabled until the filter is set again using sysfs. Fix in store_protocols() by still re-applying the filter whenever the change_protocol() driver callback succeeded. The problem can be reproduced with the img-ir driver by setting a filter, and then setting the protocol to the same protocol that is already set: $ echo nec > protocols $ echo 0xffff > filter_mask $ echo nec > protocols After this, messages which don't match the filter were still being received.

The information being requested of hardware decode callbacks through the img-ir-hw scancode API is mounting up, so combine it into a struct which can be passed in with a single pointer rather than multiple pointer arguments. This allows it to be extended more easily without touching all the hardware decode callbacks. Signed-off-by:

Removing the em28xx-rc module results in the following lockdep splat, which is caused by trying to call cancel_delayed_work_sync() on an uninitialised delayed work. Fix this by ensuring we always initialise the work. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

The default values and limits for certain controls need the knowledge of available media bus codes or link frequencies. Create such controls later on, so that most of the initialisation of the sensor has already been done when the init quirk is called.

In the case of platform data, ISPs that provide clocks to the sensor must probe before the sensor does. Accessing the sensor does require the clocks, and thus, probe cannot access the sensor in such a system. This limitation does not exist in the case of the DT.
