[PATCH v2 20/29] ABI: sysfs-class-pwm: use wildcards on What definitions

From: Mauro Carvalho Chehab
Date: Tue Sep 14 2021 - 10:35:54 EST


An "N" upper letter is not a wildcard, nor can easily be identified
by script, specially since the USB sysfs define things like.
bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl
to convert it into a Regex.
