Subject: mtd: use class_groups instead of class_attrs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=219eccdabb3a877d285b35b59cfeb242381f9d50;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: use class_groups instead of class_attrs

The class_attrs pointer is long depreciated, and is about to be finally
removed, so move to use the class_groups pointer instead.
