USB: serial/keyspan_pda, fix potential tty NULL dereferences

2011-03-01T03:24:54+00:00

Make sure that we check the return value of tty_port_tty_get.
Sometimes it may return NULL and we later dereference that.

There are several places to check. For easier handling,
tty_port_tty_get is moved directly to the palce where needed in
keyspan_pda_rx_interrupt.

tiocmset: kill the file pointer argument

2011-02-17T19:52:43+00:00

Doing tiocmget was such fun we should do tiocmset as well for the same
reasons

tiocmget: kill off the passing of the struct file

2011-02-17T19:47:33+00:00

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

USB: serial: handle Data Carrier Detect changes

2011-01-23T02:53:26+00:00

Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced
.carrier_raised function in several drivers.  That also means
tty_port_block_til_ready can now suspend the process trying to open the serial
port when Carrier Detect is low and put it into tty_port.open_wait queue.  We
need to wake up the process when Carrier Detect goes high and trigger TTY
hangup when CD goes low.

Some of the devices do not report modem status line changes, or at least we
don't understand the status message, so for those we remove .carrier_raised
again.

drivers/usb: Remove unnecessary return's from void functions

2010-08-10T12:25:42+00:00

Greg prefers this to go through the trivial tree.
http://lkml.org/lkml/2010/6/24/1

There are about 2500 void functions in drivers/usb
Only a few used return; at end of function.

Standardize them a bit.

Moved a statement down a line in drivers/usb/host/u132-hcd.c

USB serial: make USB device id constant

2010-03-02T22:54:16+00:00

The id_table field of the struct usb_device_id is constant in 
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:
