daa1c164db V4L/DVB (9778): cx18: cx18_writel_expect() should not declare success on a PCI read error
cx18: cx18_writel_expect() should not declare success on a PCI read error.
This removes the potential for cx18_write*_expect() calls to not
accomplish a PCI write successfully as expected.  The CX18-AV core uses the
*expect() calls often and this may be the source of intermittent audio
problems and standands switching problems.

tda8290 were using some random video standard for FM. This results on random
errors. Instead, program tda8290 in expert mode, using a configuration near the
one specified on NXP datasheet for tda8295 (available on their site).

Also, properly display that the device is on radio mode.

92d90f1a57 V4L/DVB (9774): tda827x: fix returned frequency
Probably due to a removed code, tda827x were doing some wrong calculus at the
returned frequency. I suspect that the original idea were to return the
programmed divisor converted into frequency again.

However, the current code is sometimes multiplying the programmed frequency by
62500, and, on other cases, like radio, it dividing it by 1000.

Instead of doing such math, let's just store the frequency value as requested by
the caller module.

eb6c96345d V4L/DVB (9770): em28xx: turn off tuner when not used
em28xx devices generally get hot when xc3028 tuner is powered on. This
patch solves this by turning power off when the device is not used, at the
expense of having a higher load time, when calling a TV application.

Since firmware load happens on 1 or 2 seconds on most devices, this is not a pain.

Also, it helps to save the planet by saving some power :)

ee2d64f5cc V4L/DVB (9720): cx18: Major rewrite of interrupt handling for incoming mailbox processing
A major rewrite of interrupt handling for incoming mailbox processing, to split
the timing critical steps from the the deferrable steps as the sending XPU on
the CX23418 will time out and overwrite our incoming mailboxes rather quickly.
Setup a pool of work "order forms" for the irq handler to send jobs to the new
work handler routine which uses the kernel default work queue to do the
deferrable work.  Started optimizing some of the cx18-io calls as they are now
the low hanging fruit for recoving microseconds back from the timeline.
Future optimizations will get rid of mmio read retries, mmio stats logging, and
combine smaller functions in the irq path into the larger ones to save ~2 us
each.
