From: Rafael J. Wysocki Date: Fri, 13 Mar 2015 00:45:49 +0000 (+0100) Subject: PNP / ACPI: Use ACPI_COMPANION_SET() during initialization X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2eb1eb02dda368fb224bf5a379d2448c742b71db;p=linux-beck.git PNP / ACPI: Use ACPI_COMPANION_SET() during initialization pnpacpi_add_device() calls acpi_bind_one() on an already registered device, which is a mistake, but it can initialize the ACPI companion field of the struct device to be registered using ACPI_COMPANION_SET() instead, so make it do that.
