From 0d5ea120abc020fada1f7cb019ec37f13162e7af Mon Sep 17 00:00:00 2001 From: Jeremy Cline Date: Fri, 5 Jan 2018 14:55:34 -0600 Subject: [PATCH] ASoC: Replace snd_soc_acpi_check_hid with acpi_dev_present Replace snd_soc_acpi_check_hid() with the generic acpi_dev_present() and remove the now unused snd_soc_acpi_check_hid function. This should have no functional change.
