From 6f08cbdaac5a3050ea1898aef8ce326030fd1117 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Thu, 14 Jan 2016 21:57:20 +0100 Subject: [PATCH] ASoC: Intel: Use acpi_dev_present() Use shiny new acpi_dev_present() and remove all the boilerplate to search for a particular ACPI device. No functional change. Cf. 2d12b6b381ba ("ACPI / utils: Add acpi_dev_present()").
