Subject: intel_pstate: Add get_scaling cpu_defaults param to Knights Landing
From: Lukasz Anaczkowski <[email protected]>
commit 69cefc273f942bd7bb347a02e8b5b738d5f6e6f3 upstream.
Scaling for Knights Landing is same as the default scaling (100000).
When Knigts Landing support was added to the pstate driver, this
parameter was omitted resulting in a kernel panic during boot.
Fixes: b34ef932d79a (intel_pstate: Knights Landing support)
