From 9d54fd6a90ff1a85b66873e67004cfe61563408a Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 4 Oct 2017 20:43:41 +0200 Subject: [PATCH] Bluetooth: hci_bcm: Make acpi_probe get irq from ACPI resources The ACPI subsys is going to move over to instantiating ACPI enumerated HCIs as serdevs, rather then as platform devices. So we need to make bcm_acpi_probe() suitable for use on non platform- devices too, which means that we cannot rely on platform_get_irq() getting called. This commit modifies bcm_acpi_probe() to directly get the irq from the ACPI resources, this is a preparation patch for adding (runtime)pm support to the serdev path.
