From 1cc194caaffbe07b8e08d464d8c309bc8e824618 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 2 Aug 2018 16:57:17 +0200 Subject: [PATCH] Bluetooth: btrtl: Add support for a config filename postfix The contents of the rtl_bt/rtlXXXX_config.bin file may be board specific allow the caller of btrtl_initialize to specify a postfix identifying the board, which if specified will make btrtl_initialize look for rtl_bt/rtlXXXX_config-.bin instead.
