Subject: gpiomon: initialize the active low variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=55d36adc16fa9e297c4d81ecbf8d41aa6b66de87;p=qemu-gpiodev%2Flibgpiod.git

gpiomon: initialize the active low variable

The variable active_low is not initialized, so the value is undefined
and if the -l argument is not passed, the undefined value remains. Fix
it by initializing it to false.
