yes, I mean carrier's frequency. I didn't understand that
LIRC_SET_SEND_CARRIER was related to the frequency.

You're right; the first idea was to submit also the device
driver, but then I decided to keep it separate from this
patchset.
Anyway, we can drop this one (it's the last of the series) and,
in case it will be needed after the above comment, I will re-send
it with the driver.
