Subject: [PATCH] dm sysfs: use default_groups in kobj_type
Git-commit: eaac0b590a47c717ef36cbfd1c528cd154c965a1
Patch-mainline: v5.17-rc1
References: jsc#PED-2765
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 dm 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.
