Alexey Khoroshilov 221b7b5796 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.
