USB: serial: ftdi: correct merge conflict with CONTEC id

2010-06-30T15:16:06+00:00

This patch corrects a problem with the merge of a previous
patch to add the CONTEC identifier.

I believe the merge problem occurred with the commit:
dee5658b482e9e2ac7d6205dc876fc11d4008138

Originally I submitted a patch and then they asked me to order the IDs
and resubmit, so did I. But unfortunately in the end somehow both
patches were merged.

USB: serial: digi_acceleport: Eliminate a NULL pointer dereference

2010-06-04T20:16:19+00:00

If port is NULL, then the call to dev_err will dereference a value that is
a small offset from NULL.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@r exists@
expression E,E1;
identifier f;
statement S1,S2,S3;
@@

if ((E == NULL && ...) || ...)
{
  ... when != if (...) S1 else S2
      when != E = E1
* E->f
  ... when any
  return ...;
}
else S3
//

USB: ftdi_sio: fix DTR/RTS line modes

2010-06-04T20:16:19+00:00

Call set_mctrl() and clear_mctrl() according to the flow control mode
selected. This makes serial communication for FT232 connected devices
work when CRTSCTS is not set.

This fixes a regression introduced by 4175f3e31 ("tty_port: If we are
opened non blocking we still need to raise the carrier"). This patch
calls the low-level driver's dtr_rts() function which consequently sets
TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in
cflags, however, does not reset these bits, and so data is not actually
sent out on the serial wire.

USB: kl5usb105: reimplement using generic framework

2010-05-20T20:21:50+00:00

Kill custom read and write implementations (static per-port,
singleton(!) urb pool).

Also remove changelog header (can be retrieved through git).

Read processing and write-buffer handling tested using a cp210x device
in a loopback setup.
