From: Christophe JAILLET Date: Sun, 5 May 2024 07:03:32 +0000 (+0200) Subject: leds: is31fl319x: Constify struct regmap_config X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4a598907ef1f812ec3fecac5c181c0b7b2d21913;p=users%2Fjedix%2Flinux-maple.git leds: is31fl319x: Constify struct regmap_config 'is31fl3190_regmap_config' and 'is31fl3196_regmap_config' are not modified in this diver and are only used as a const struct regmap_config. Constifying these structures moves some data to a read-only section, so increase overall security.
