Jani,

In hindsight I should have put the link to this bugzilla in that patch as:

Related: https://bugs.freedesktop.org/show_bug.cgi?id=96571

And not as:

BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=96571

Sorry.

As for this bug, as I tried to explain in comment 63, this has been (mostly)
fixed for close to 2 years now, at least for configs which build the i915
driver as a module, as almost all generic distro kernels do. So with my Fedora
distro contributor had on I consider this bug fixed.

If you want to keep it open to track the i915 builtin case, I suggest changing
the summary too:

BYT/CHT: pwm vs i915 driver initialization order when i915 is builtin

To reflect that:
1) This is a generic BYT/CHT issue, not Surface 3 specific
2) This only is a problem when the i915 driver is builtin
