Subject: speedstep-ich: use correct CPU in speedstep_get()
From: Dave Mueller <dave.mueller@xxxxxx>
It looks like commit 394122ab144dae4b276d74644a2f11c44a60ac5c ("cpumask:
avoid playing with cpus_allowed in speedstep-ich.c") broke the
speedstep-ich driver.
The problem seems to be that speedstep-lib.c:speedstep_get_frequency() is
called with a wrong value as "processor" parameter by the code below,
resulting in a return value of 0. The "processor" parameter should be the
value returned by "speedstep_detect_processor()"
