From: Zhao Qiang <qiang.zhao@nxp.com>
Date: 2017-03-14 01:52:44
1. modify bd_status from u32 to u16 in function hdlc_rx_done, because bd_status register is 16bits 2. write bd_length register before writing bd_status register Signed-off-by: Zhao Qiang <qiang.zhao@nxp.com> --- drivers/net/wan/fsl_ucc_hdlc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
