Message-ID: <12163052.O9o76ZdvQC@kreacher> Date: Thu, 02 Mar 2023 18:49:12 +0100 From: "Rafael J. Wysocki" <rjw@...ysocki.net> To: Linux ACPI <linux-acpi@...r.kernel.org> Cc: LKML <linux-kernel@...r.kernel.org> Subject: [PATCH] ACPI: docs: Update the pm_profile sysfs attribute documentation From: Rafael J. Wysocki <rafael.j.wysocki@...el.com> The list of possible pm_profile values listed in sysfs-acpi-pmprofile does not include the tablet one (8), so update it. While at it, rewrite the description so it is more accurate and somewhat easier to follow. Signed-off-by: Rafael J.
