This is a resend of a patch i submitted a few days ago although with a mangled formatting. I don't know who maintains the PL011 AMBA driver, so I hope someone steps up and helps me in bringing this upstream. There is a problem with the logic of tx_empty in the amba-pl011 serial port driver. Instead of checking for an empty FIFO it checks for a not-full FIFO, which - according to Documentation/serial/driver - is wrong. Thanks, Simon Simon Budig (1): Fix logic of tx_empty. drivers/tty/serial/amba-pl011.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
