The mxs-auart driver does not count FIFO overrun errors. These errors never appear in /proc/tty/driver/ttyAPP. This is because the OERR status bit is masked by read_status_mask in the rx interrupt function, but the AUART_STAT_OERR bit is never set in read_status_mask. The patch enables the counting of overrun errors. Signed-off-by: Wolfgang Ocker <weo@reccoware.de> --- drivers/tty/serial/mxs-auart.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 2.10.0
