Subject[PATCH] gpiolib: of: Update debug messages for of_get_named_gpiod_flags
Date
Following is the debug output (only a few examples) before and after the patch.

$ dmesg | grep of_get_named_gpiod_flags

Before:
of_get_named_gpiod_flags: can't parse gpios property of node '/mmc@12220000[0]'
of_get_named_gpiod_flags exited with status 0

After:
of_get_named_gpiod_flags: can't parse 'wp-gpios' property of node '/mmc@12220000[0]'
of_get_named_gpiod_flags: parsed 'gpios' property of node '/gpio-keys/power[0]' - status (0)
