    drivers/media/i2c/ir-kbd-i2c.c: In function ‘get_key_haup_common’:
    drivers/media/i2c/ir-kbd-i2c.c:120: warning: ‘toggle’ is used uninitialized in this function

To fix this, use the intermediate "toggle" variable, like is done in
other branches.

Fixes: 00bb820755ed8ee9 ("[media] rc: Hauppauge z8f0811 can decode RC6")
