From: Thomas Weißschuh Date: Sat, 6 Jul 2024 11:13:42 +0000 (+0200) Subject: regmap-irq: handle const struct regmap_irq_sub_irq_map X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f21711bbdbf0d95a389bfaad54ce444b46830d58;p=users%2Fdwmw2%2Flinux.git regmap-irq: handle const struct regmap_irq_sub_irq_map The struct instances supplied by the drivers are never modified. Handle them as const in the regmap core allowing the drivers to put them into .rodata. Also add a new entry to const_structs.checkpatch to make sure future instances of this struct already enter the tree as const.
