From d306cbbc34cc9aa6ed2235472110fe797f887db7 Mon Sep 17 00:00:00 2001 From: Atharva Tiwari Date: Tue, 7 Oct 2025 18:35:10 +0530 Subject: mfd: macsmc: Make SMC write buffers const Mark the write buffer arguments in apple_smc_write(), apple_smc_rw(), and apple_smc_write_atomic() as const. These functions do not modify the data provided by the caller, so the parameters should be const qualified.
