From: Raviteja Narayanam <redacted> [ Upstream commit 42e11948ddf68b9f799cad8c0ddeab0a39da33e8 ] On some platforms, the log is corrupted while console is being registered. It is observed that when set_termios is called, there are still some bytes in the FIFO to be transmitted. So, wait for tx_empty inside cdns_uart_console_setup before calling set_termios.

Thanks, I've queued up the dependant patch, somehow Sasha's builders must have missed this :) greg k-h _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
