Some printk() debugging showed that vidioc_s_hw_freq_seek() setups
radio->curfreq to out of range value (lines 395-396) and calls
amradio_set_freq() to set this frequency on device without any
out-of-range checks.

Patch protects from setting up frequency on device to incorrect value
moving clamp_t check inside amradio_set_freq. With this patch we can
call amradio_set_freq() with out of range frequency from any place.
Also put comment that sometimes radio->curfreq is set to out of range
value in vidioc_s_hw_freq_seek().

Greg Kroah-Hartman ecb3b2b35d USB: convert drivers/media/* to use module_usb_driver()
This converts the drivers in drivers/media/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

Alexey Dobriyan 405f55712d headers: smp_lock.h redux
* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Alessio Igor Bogani 24c44d8511 V4L/DVB (11842): radio-mr800.c: missing mutex include
radio-mr800.c uses struct mutex, so while <linux/mutex.h> seems to be
pulled in indirectly by one of the headers it already includes, the right
thing is to include it directly.
