Commit 38a07311 ("[media] omap: be sure that MMU is there for COMPILE_TEST") added a dependency on HAS_MMU. There's no Kconfig symbol HAS_MMU. Use MMU instead. Signed-off-by:

au0828 IR stop and poll routines continue to access device while usb disconnect is in progress. There is small window between device disconnect and usb interface is set to null. This results in filling the log with several of the following error messages. Fix it to detect device disconnect condition and avoid device access.

Terratec Cinergy T2 Stick HD [eb1a:8179] is a USB DVB-T/T2/C tuner that contains following components: * Empia EM28178 USB bridge * Silicon Labs Si2168-A30 demodulator * Silicon Labs Si2146-A10 tuner I don't have the remote, so the RC_MAP is a best guess based on the pictures of the remote controllers and other supported Terratec devices with a similar remote.

The Silicon Labs Si2146 tuner seems to work with the same driver as the Si2157, but there a few exceptions. The powerup command seems to be quite a bit different. In addition there's a property 0207 that requires a different value. Thus another entry is created in the si2157_id table to support also si2146 in this driver. The datasheet is available on manufacturer's website: http://www.silabs.com/support%20documents/technicaldocs/Si2146-short.pdfSigned-off-by:

By default dma_map_sg syncs the mapped buffer to the device. But buf_prepare expects a buffer syncs for the cpu and the buffer will be synced to the device in the prepare memop. The reverse is true for dma_unmap_sg, buf_finish and the finish memop. To prevent unnecessary syncs we ask dma_(un)map_sg to skip the sync. Signed-off-by:

This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.

The 'write' argument is very ambiguous. I first assumed that if it is 1, then we're doing video output but instead it meant the reverse. Since it is used to setup the dma_dir value anyway it is now replaced by the correct dma_dir value which is unambiguous. Signed-off-by:

In order to make use of the vb2 queue start/stop_streaming operations the video and queue enable/disable operations need to be split, as the vb2 queue will need to enable and disable video instead of the other way around. Also move buffer queue disable outside of uvc_video_resume() to remove all queue disable operations out of uvc_video.c. Signed-off-by:
