Subject: [PATCH v11 4/8] cpufreq: amd-pstate: Remove amd_get_{min,max,nominal,lowest_nonlinear}_freq()
Date: Tue, 23 Apr 2024 15:58:20 +0800 [thread overview]
Message-ID: <b5f879afc707249652c2c65a08a95a38404e7a59.1713858800.git.perry.yuan@amd.com> (raw)
In-Reply-To: <cover.1713858800.git.perry.yuan@amd.com>
From: "Gautham R. Shenoy" <gautham.shenoy@amd.com>
amd_get_{min,max,nominal,lowest_nonlinear}_freq() functions merely
return cpudata->{min,max,nominal,lowest_nonlinear}_freq values.
There is no loss in readability in replacing their invocations by
accesses to the corresponding members of cpudata.
Do so and remove these helper functions.
