Subject: [PATCH v2 05/10] firmware: arm_scpi: convert platform driver to use dev_groups

From: Greg Kroah-Hartman <[email-masked]>
Date: Wed, 31 Jul 2019 14:43:44 +0200

Platform drivers now have the option to have the platform core create
and remove any needed sysfs attribute files.  So take advantage of that
and do not register "by hand" a sysfs group of attributes.
