Recent rtl28xxu patch I made moved demod ADC enable from power control
to frontend control (due to slave demod support). Because of that we
need call USB interface frontend control too in order to enable ADC.

The function releases the queue if the file being released is the queue
owner. The check reads the queue->owner field without taking the queue
lock, creating a race condition with functions that set the queue owner,
such as vb2_ioctl_reqbufs() for instance.
Fix this by moving the queue->owner check within the mutex protected
section.

The vb2_fop_poll() implementation tries to be clever on whether it needs
to lock the queue mutex by checking whether polling might start fileio.
The test requires reading the q->num_buffer field, which is racy if we
don't hold the queue mutex in the first place.
Remove the extra cleverness and just lock the mutex.

Amlogic Meson SoCs include a infrared remote control receiver that can
operate in two modes: "NEC" mode in which the hardware decodes frames
using the NEC IR protocol, and "general" mode in which the receiver
simply reports the duration of pulses and spaces for software
decoding.
This is a driver for the IR receiver that implements software decoding
of received frames.

* Silicon Labs Si2168-A30 demodulator

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.
