From: Ville Syrjälä Date: Wed, 8 Jan 2020 18:12:42 +0000 (+0200) Subject: drm/i915/dvo: Make .get_modes() return the number of modes X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4a2236f9a74a37d1737d3ceff980b1945ded43be;p=linux.git drm/i915/dvo: Make .get_modes() return the number of modes .get_modes() is supposed to return the number of modes added to the probed_modes list (not that anyone actually checks for anything except zero vs. not zero). Let's do that.
