[Intel-gfx] [PATCH v2 0/8] drm/i915/lspcon: Work around resume failure

[Imre Deak]

This is v2 of [1] addressing the review comments from Jani and Shashank.
Meanwhile I also checked that the SKL-6700 machine reported in bugzilla
(see the last patch) had the same problem as the APL where I saw this
first and the workaround seems to solve the problem there too.
