From d9962f6f428449fe227f1c88c65ac3fffdf7dceb Mon Sep 17 00:00:00 2001 From: Rikard Falkeborn Date: Wed, 14 Apr 2021 20:12:48 +0300 Subject: [PATCH] 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.
