[PATCH can-next 2/2] can: rockchip_canfd: rkcanfd_handle_error_int_reg_ec(): fix decoding of error code register
From: Marc Kleine-Budde
Date: Wed Sep 11 2024 - 04:46:12 EST
Probably due to a copy/paste error rkcanfd_handle_error_int_reg_ec()
checks twice if the RKCANFD_REG_ERROR_CODE_TX_ACK_EOF bit is set in
reg_ec.
Keep the correct check for RKCANFD_REG_ERROR_CODE_TX_ACK_EOF and
remove the superfluous one.
