Subject: [PATCH] cpufreq: docs: Add missing cpuinfo_cur_freq description
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Add a description of the cpuinfo_cur_freq policy attribute in sysfs
to the cpufreq documentation under Documentation/admin-guide/pm/ as
it is missing after commit 2a0e49279850 (cpufreq: User/admin
documentation update and consolidation) that overlooked it.
Fixes: 2a0e49279850 (cpufreq: User/admin documentation update and consolidation)
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
