Subject: intel_th: Constify attribute_group structs
X-Git-Tag: accepted/tizen/unified/20230118.172025~7416^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d9962f6f428449fe227f1c88c65ac3fffdf7dceb;p=platform%2Fkernel%2Flinux-rpi.git

intel_th: Constify attribute_group structs

The only usage of them is to pass their address to sysfs_create_group()
and sysfs_remove_group(), both which have pointers to const
attribute_group structs as input. Make them const to allow the compiler
to put them in read-only memory.
