Subject: Char: cyclades, fix potential NULL dereference
From: Jiri Slaby <jirislaby@xxxxxxxxx>
t=To ztxdone is jumped even if tty is NULL and tty_wakeup placed after this
label doesn't expect NULLed parameter, so this will cause an oops in some
situations (why they scheduled a wakeup there before remove bottom half
processing patch?). wakeup only in the case when we have non-null tty
struct.
Spotted by Adrian Bunk.
