Subject: chip: use a temporary variable in gpiod_chip_close()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2dd161704ca87966ff8cf78e4c861cd8a6db6322;p=qemu-gpiodev%2Flibgpiod.git

chip: use a temporary variable in gpiod_chip_close()

The code looks better if we use a temporary pointer to gpiod_line.
