Subject: [PATCH] md: use default_groups in kobj_type
Date:   Thu,  6 Jan 2022 11:03:35 +0100

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the md rdev sysfs code to use default_groups field which
has been the preferred way since aa30f47cf666 ("kobject: Add support for
default attribute groups to kobj_type") so that we can soon get rid of
the obsolete default_attrs field.
