These were independently reported in 2 configurations, and I confirmed with another. I think those went upstream via Michael's tree, but he's away at the moment so if you would be able to consider them for the tty tree that would be appreciated. Thanks, Nick Nicholas Piggin (3): tty: hvc: hvc_poll() fix read loop hang tty: hvc: hvc_poll() fix read loop batching tty: hvc: hvc_write() fix break condition drivers/tty/hvc/hvc_console.c | 38 ++++++++++++++++++++++++++++++----- 1 file changed, 33 insertions(+), 5 deletions(-) -- 2.18.0
