Subject: gpiomon: fix parsing of custom output formats
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2100f6e66a4ad02d0c390a1d3df1c1cb421d3221;p=qemu-gpiodev%2Flibgpiod.git

gpiomon: fix parsing of custom output formats

The '%%e' string should be printed as '%e' - the same as for printf()
format specifiers - but gpiomon prints '%%e' in this case. Fix it.
