From 96a621e01a42dc53848e2e4915fd807ebc1fc82f Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 24 May 2018 15:10:21 -0500 Subject: [PATCH] PCI: shpchp: Remove get_hp_hw_control_from_firmware() wrapper get_hp_hw_control_from_firmware() is a trivial wrapper around acpi_get_hp_hw_control_from_firmware(), probably intended to be generic in case other firmware needed similar OS/platform negotiation. Remove get_hp_hw_control_from_firmware() and call acpi_get_hp_hw_control_from_firmware() directly. Add a stub for acpi_get_hp_hw_control_from_firmware() for the non-ACPI case.
