Malcolm Priestley 15e1ce3318 [media] lmedm04: Fix usb_submit_urb BOGUS urb xfer, pipe 1 != type 3 in interrupt urb
A quirk of some older firmwares that report endpoint pipe type as PIPE_BULK
but the endpoint otheriwse functions as interrupt.

Check if usb_endpoint_type is USB_ENDPOINT_XFER_BULK and set as usb_rcvbulkpipe.

Antti Palosaari b410dae43c [media] rtl2832: implement own lock for regmap
Introduce own lock to silence lockdep warning. lockdep validator
makes wrong decision when two similar (&map->mutex) locks were taken
recursively, even those are different mutexes in a two different
drivers. After that patch, functionality remains same, but mutex names
are different. That is a temporary hack, proper solution is make
regmap aware of locked nested locking rules.

Antti Palosaari 0d117901b6 [media] rtl2832: remove internal mux I2C adapter
There was 2 muxed I2C adapters, one for demod tuner bus and one for
internal use. Idea of internal I2C adapter was to force I2C repeater
close when demod access its registers. Driver has also delayed work
queue based method to close I2C repeater.

After regmap conversion internal I2C adapter based repeater close
left unused - only work queue method was in use. We could not use
internal mux adapter method with regmap as it makes recursive regmap
call, which causes deadlock as regmap has own locking. Due to that
remove whole method totally.
