The monspecs structure is only copied into another structure, so make it const. The opportunity for this change was found using Coccinelle.

Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

This function lost its only call site as part of
earlier dead code removal, so remove it as well:

The cpufreq policy notifier's CPUFREQ_ADJUST notification is going to get removed soon. The notifier callback sa1100fb_freq_policy() isn't doing anything apart from printing a debug message on CPUFREQ_ADJUST notification. There is no point in keeping an otherwise empty callback and registering the notifier. Remove it.

Motivated because it contains a struct display, which is a fbcon internal data structure that I want to rename. It seems to have been formerly used in drivers, but that's very long time ago.
