Subject: drm/nouveau/secboot: abstract fixup_hs_desc function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9bb55bb79f480d6422db55f0ed5052d3b0a2d22e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/nouveau/secboot: abstract fixup_hs_desc function

As different firmare versions use different HS descriptor formats, we
need to abstract this part as well.
