From 32e7e06f60e78bca28fc6bb7f9dd54177750c331 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 14 Sep 2022 04:59:53 -0700 Subject: scsi: aic79xx: Use __ro_after_init explicitly ahd_linux_setup_iocell_info() intentionally writes to the const-marked aic79xx_iocell_info array, but is called during __init, so the location is actually writable at this point on most architectures. Annotate this explicitly with __ro_after_init to avoid static analysis confusion.
