From 2256b8d2ff6c8e994161ab15b6e6d0314d3174ae Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 20 Jan 2016 12:46:24 +0100 Subject: [PATCH] ASoC: rt5659: avoid unused variable warning for rt5659_acpi_match The newly added rt5659 codec driver unconditionally defines an ACPI device match table but then uses ACPI_PTR() to remove the only reference to it, so we get a harmless build warning: sound/soc/codecs/rt5659.c:4200:30: warning: 'rt5659_acpi_match' defined but not used [-Wunused-variable] static struct acpi_device_id rt5659_acpi_match[] = { This changes both the OF match table and the ACPI match table to follow the same style, using ACPI_PTR/of_match_ptr to make the reference conditional, and using an #ifdef to hide the table. This also adds the missing MODULE_DEVICE_TABLE for the OF case and adapts the formatting to the same style.
