Subject: staging: sm750fb: Mark g_noaccel, g_nomtrr and g_dualview as __ro_after_init
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=ddf58ed94154c883590c58ceec05b77cacf5805e;p=thirdparty%2Fkernel%2Flinux.git

staging: sm750fb: Mark g_noaccel, g_nomtrr and g_dualview as __ro_after_init

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.
