Subject: thunderbolt: Constify static attribute_group structs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6889e00f0e138beeb775e38decf59959b079ae6f;p=linux.git

thunderbolt: Constify static attribute_group structs

The only usage of these is to put their addresses in arrays of pointers
to const attribute_groups. Make them const to allow the compiler to put
them in read-only memory.
