From 230b04ac8f439d0797ab85fb356f069f0472306f Mon Sep 17 00:00:00 2001 From: Tedd Ho-Jeong An Date: Tue, 28 Jun 2016 08:56:39 -0700 Subject: [PATCH] Bluetooth: Replace constant hw_variant from Intel Bluetooth firmware filename The format of Intel Bluetooth firmware filename for bootloader product is ibt--.sfi Currently the driver uses a constant value 11 (0x0b) for hw_variant to support LnP/SfP product. But new product like WsP product has a different value such as 12 (0x0c). To support the multiple products, this patch replaces the constant value of hw_variant to the actual hw_variant value read from the device.
