gpio: mockup: extend the debugfs layout (ca8792af) · Commits · 戴 / test

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. Signed-off-by:
