Fallback to FW v1 otherwise. This behavior is only for RTL8852C. Fixes: 9a24ce5e29b1 ("Bluetooth: btrtl: Firmware format v2 support") Cc: stable@vger.kernel.org Suggested-by: Juerg Haefliger Tested-by: Hilda Wu Signed-off-by: Max Chou --- Changes in v4: - Reduce the commit log. Thanks Juerg! - Correct the tag for Fixes and Cc. Thanks Thorsten! Changes in v3: - Fix commit log for CheckPatch FAIL Changes in v2: - Tuning the code for more readable. Thanks Juerg! - Modify the commit log. --- drivers/bluetooth/btrtl.c | 70 +++++++++++++++++++++++++-------------- 1 file changed, 45 insertions(+), 25 deletions(-) diff --git a/drivers/bluetooth/btrtl.c b/drivers/bluetooth/btrtl.c index ddae6524106d..84c2c2e1122f 100644 --- a/drivers/bluetooth/btrtl.c +++ b/drivers/bluetooth/btrtl.c @@ -104,7 +104,7 @@ static const struct id_table ic_id_table[] = { { IC_INFO(RTL_ROM_LMP_8723A, 0xb, 0x6, HCI_USB), .config_needed = false, .has_rom_version = false, -
