The ir-rc from my MSI DigiVox mini II Version 3 (af9015) will not work since
kernel 3.2.x.

sudo ir-keytable -t shows:

	1348890734.303273: event MSC: scancode = 317
	1348890734.303280: event key down: KEY_POWER (0x0074)
	1348890734.303282: event sync
	1348890734.553961: event key up: KEY_POWER (0x0074)
	1348890734.553963: event sync
	1348890741.303451: event MSC: scancode = 30d
	1348890741.303457: event key down: KEY_DOWN (0x006c)
	1348890741.303459: event sync
	1348890741.553956: event key up: KEY_DOWN (0x006c)

So I changed in rc-msi-digivox-ii.c { 0x0002, KEY_2 }, to { 0x0302, KEY_2 },
and so on. And now it works well.

The tda18271 datasheet says:
	"The image rejection calibration and RF tracking filter
	 calibration must be launched exactly as described in the
	 flowchart, otherwise bad calibration or even blocking of the
	 TDA18211HD can result making it impossible to communicate
	 via the I2C-bus."
(yeah, tda18271 refers there to tda18211 - likely a typo at their
 datasheets)
That likely explains why sometimes tda18271 stops answering. That
is now happening more often on designs with drx-k chips, as the
firmware is now loaded asyncrousnly there.
While the above text doesn't explicitly tell that the I2C bus
couldn't be used by other devices during such initialization,
that seems to be a requirement there.
So, let's explicitly use the I2C lock there, avoiding I2C bus
share during those critical moments.
Compile-tested only. Please test.

"carrier" comes from a get_user() in ir_lirc_ioctl().  We need to test
that it's not zero before using it as a divisor.  It might have been
nice to test for this ir_lirc_ioctl() but the mceusb driver uses zero to
disable carrier modulation.
The bug in redrat3 is a little more subtle.  The ->carrier is passed to
mod_freq_to_val() which uses it as a divisor.
