From b7da6a69defd195da66bfd6b35efeb376a252557 Mon Sep 17 00:00:00 2001 From: Tedd Ho-Jeong An Date: Mon, 6 Mar 2017 15:38:32 -0800 Subject: [PATCH] Bluetooth: hci_intel: Fix firmware file name to use hw_variant The format of Intel Bluetooth firmware for bootloader product is ibt--.sfi and .ddc. This patch uses a hw_variant value read from the device during runtime to form the firmware filenames instead of using a constant value, so it can support multiple prouducts.
