Subject: [PATCH 2/9] Revert "cpufreq: intel_pstate: Replace bxt_funcs with core_funcs"
Date: Tue, 27 Mar 2018 23:38:38 -0700	[thread overview]
Message-ID: <20180328063845.4884-3-currojerez@riseup.net> (raw)
In-Reply-To: <20180328063845.4884-1-currojerez@riseup.net>

This reverts commit dbd49b85eec7eb6d7ae61bad8306d5cdd85c142d.  A
future commit will introduce a new update_util implementation for LP
platforms, so the bxt_funcs table comes in handy.
