Subject: [PATCH 4/9] Revert "cpufreq: intel_pstate: Simplify intel_pstate_adjust_pstate()"
Date: Tue, 27 Mar 2018 23:38:40 -0700	[thread overview]
Message-ID: <20180328063845.4884-5-currojerez@riseup.net> (raw)
In-Reply-To: <20180328063845.4884-1-currojerez@riseup.net>

This reverts commit a891283e56362543d1d276e192266069ef52075b.  The
previous approach of taking an explicit P-state target as argument
makes it more easily reusable by a future commit.
