Subject: s390/cio: constify attribute_group structures.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f460d113c6805e953cbcafb5e10b6c0edf5a55aa;p=linux.git

s390/cio: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.
