From ca8792af40afb1e83e6910eac1bc48a91694fba3 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 27 Nov 2017 11:48:45 +0100 Subject: [PATCH] gpio: mockup: extend the debugfs layout Currently each chip has a dedicated directory in debugfs for event triggers. We use the chip's label for the directory name, but the user can't really associate these directories with chip names without parsing the relevant sysfs entries. Use chip names for directory names. For backward compatibility: create links pointing to the actual directories named using the chip labels.
