2020-10-27drm: drm_edid: remove a duplicated kernel-doc declarationMauro Carvalho Chehab
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.

2020-10-09ALSA: hda/i915 - fix list corruption with concurrent probesTakashi Iwai
Current hdac_i915 uses a static completion instance to wait for i915 driver to complete the component bind. This design is not safe if multiple HDA controllers are active and communicating with different i915 instances, and can lead to list corruption and failed audio driver probe. Fix the design by moving completion mechanism to common acomp code and remove the related code from hdac_i915.

2020-09-09drm: allow limiting the scatter list size.Gerd Hoffmann
Add drm_device argument to drm_prime_pages_to_sg(), so we can call dma_max_mapping_size() to figure the segment size limit and call into __sg_alloc_table_from_pages() with the correct limit. This fixes virtio-gpu with sev. Possibly it'll fix other bugs too given that drm seems to totaly ignore segment size limits so far ... v2: place max_segment in drm driver not gem object. v3: move max_segment next to the other gem fields. v4: just use dma_max_mapping_size().
