From 3b4feb21158f873269ff3fbe2fe8d23a88d64b24 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 10 Nov 2020 15:27:24 +0100 Subject: gpio: sysfs: Enforce character device If users select sysfs support they get the character device as well so that end-users cannot complain that they "only have sysfs on my system". They should have the character device at all times. If someone is in so dire need of stripping out the character device while still enabling the sysfs ABI they can very well patch the kernel. Also only show this obsolete option to expert users.
