24e83d41 - ABI: sysfs-class-pwm: use wildcards on What definitions

Thu, 16 Sep 2021 08:59:47 +0000

ABI: sysfs-class-pwm: use wildcards on What definitionsAn "N" upper letter is not a wildcard, nor can easily be identifiedby script, specially since the USB sysfs define things like.bNumInterfaces. Use, instead, , in order to let script/get_abi.plto convert it into a Regex.Signed-off-by: Mauro Carvalho Chehab Link: https://lore.kernel.org/r/eb3edca0f3cf693d8d28ee7bd00339cac2039014.1631782432.git.mchehab+huawei@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-pwm
