pcmcia: synclink_cs: fix potential tty NULL dereference
tty_port_tty_get() can return NULL after port hangup that may happen anytime. The patch adds checks that tty_port_tty_get() returns nonNULL around places where tty is actually used. I have no actual hardware to test the patch, so I have updated rx side processing from common sense only. v2: rx handling updated according Alan Cox feedback. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
