The patch titled
usb-serial: fix oti6858.c segfault in termios handling
has been removed from the -mm tree. Its filename was
usb-serial-fix-oti6858c-segfault-in-termios-handling.patch
This patch was dropped because it was nacked
------------------------------------------------------
Subject: usb-serial: fix oti6858.c segfault in termios handling
From: Thomas Viehmann <tv@xxxxxxxxxx>
The oti6858 usb serial driver should use kernel_termios_to_user_termios/
user_termios_to_kernel_termios to avoid segfaults because the kernel uses a
structure differing from that of user space with a different size.
