Subject: UIO: convert class code to use dev_groups
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c9dce927e96c002856ac93b3a43115c33b6c1a74;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

UIO: convert class code to use dev_groups

The dev_attrs field of struct class is going away soon, dev_groups
should be used instead.  This converts the uio class code to use the
correct field.
