Subject: [PATCH] staging: sm750fb: Mark g_noaccel, g_nomtrr and g_dualview as __ro_after_init
Date: Sat, 16 May 2026 14:23:21 +0000 [thread overview]
Message-ID: <20260516142326.36018-1-len.bao@gmx.us> (raw)
The 'g_noaccel', 'g_nomtrr' and 'g_dualview' variables are initialized
only during the init phase in the 'lynxfb_setup' function and never
changed. So, mark them as __ro_after_init.
