From: Ricardo B. Marliere Date: Tue, 5 Mar 2024 19:00:45 +0000 (-0300) Subject: regulator: core: make regulator_class constant X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4fe6207508d6525e87149348daeafde152ba672c;p=linux.git regulator: core: make regulator_class constant Since commit 43a7206b0963 ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the regulator_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.
