[PATCH] leds: turris-omnia: convert to use dev_groups
Posted by Greg Kroah-Hartman 3 years, 8 months ago
The driver core supports the ability to handle the creation and removal
of device-specific sysfs files in a race-free manner.  Take advantage of
that by converting this driver to use this by moving the sysfs
attributes into a group and assigning the dev_groups pointer to it.
