drm/edid: Remove defunct EDID_QUIRK_FIRST_DETAILED_PREFERRED (9d5549d8) · Commits · 戴 / test

Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything. Its counterpart in f86EdidModes.c is properly hooked up but somehow that functionality was lost when it was copied into the kernel. The concensus seems to be that this quirk is a bit misguided anyway so let's nuke the leftovers. For posterity here are some links to known cases: * Proview AY765C https://bugs.freedesktop.org/show_bug.cgi?id=15160 * Unknown Acer https://bugzilla.redhat.com/show_bug.cgi?id=284231 (got the reference from xf86EdidModes.c) * Peacock Ergovision 19 (only in xf86EdidModes.c) https://bugzilla.redhat.com/show_bug.cgi?id=492359 * Philips 107p5 CRT "Reported on xorg@ with pastebin", didn't find the mail(s) Cc: Adam Jackson <ajax@redhat.com> Signed-off-by:
