A recent rework accidentally left a debugging printk untouched
while changing the meaning of the variables, leading to an
uninitialized variable being printed:
drivers/media/i2c/ir-kbd-i2c.c: In function 'get_key_haup_common':
drivers/media/i2c/ir-kbd-i2c.c:62:2: error: 'toggle' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This prints the correct one instead, as we did before the patch.
Fixes: 00bb820755ed ("[media] rc: Hauppauge z8f0811 can decode RC6")

I submitted this repeatedly as it is a v4.9 regression, but
I never saw a reply for it.
