This is a note to let you know that I have just added a patch titled sunsab: Fix detection of BREAK on sunsab serial console to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 0e3ef547fa71186c84f8b866d852077956795c61 Mon Sep 17 00:00:00 2001 From: Christopher Alexander Tobias Schulze <cat.schulze@alice-dsl.net> Date: Sun, 3 Aug 2014 16:01:53 +0200 Subject: sunsab: Fix detection of BREAK on sunsab serial console commit fe418231b195c205701c0cc550a03f6c9758fd9e upstream. Fix detection of BREAK on sunsab serial console: BREAK detection was only performed when there were also serial characters received simultaneously. To handle all BREAKs correctly, the check for BREAK and the corresponding call to uart_handle_break() must also be done if count == 0, therefore duplicate this code fragment and pull it out of the loop over the received characters. Patch applies to 3.16-rc6. Signed-off-by: Christopher Alexander Tobias Schulze <cat.schulze@alice-dsl.net> Signed-off-by: David S.
