Subject: [PATCH 22/33] fbcon: Call fbcon_mode_deleted/new_modelist directly
Date: Fri, 24 May 2019 10:53:43 +0200	[thread overview]
Message-ID: <20190524085354.27411-23-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20190524085354.27411-1-daniel.vetter@ffwll.ch>

I'm not entirely clear on what new_modelist actually does, it seems
exclusively for a sysfs interface. Which in the end does amount to a
normal fb_set_par to check the mode, but then takes a different path
in both fbmem.c and fbcon.c.

I have no idea why these 2 paths are different, but then I also don't
really want to find out. So just do the simple conversion to a direct
function call.

v2: static inline for the dummy versions, I forgot.
