drm/displayid: add separate drm_displayid.c

2021-03-31T12:41:35+00:00

We'll be adding more DisplayID specific functions going forward, so start off by splitting out a few functions to a separate file. We don't bother with exporting the functions; at least for now they should be needed solely within drm.ko. No functional changes.

drm: drm_edid: remove a duplicated kernel-doc declaration

2020-10-27T10:20:55+00:00

It is not possible to create cross-references for duplicated symbols. While Sphinx always detected it, on Sphinx 3 it generates warnings like this: .../Documentation/gpu/drm-kms-helpers:326: ../drivers/gpu/drm/drm_edid.c:1626: WARNING: Duplicate C declaration, also defined in 'gpu/drm-kms-helpers'. Declaration is 'bool drm_edid_are_equal (const struct edid *edid1, const struct edid *edid2)'. So, get rid of the duplicated kernel-doc markup.
