module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

USB: serial: remove unnecessary reinitialisations of urb->dev

2011-11-15T18:33:16+00:00

Remove unnecessary reinitialisations of urb->dev before each submission,
which were based on the (no longer valid) assumption that serial->dev
will be set to NULL on close.

Compile-only tested.

usb/serial: fix function args warnings, dropping *filp

2011-04-04T15:35:20+00:00

Fix build warnings caused by removal of *filp arg in struct
usb_serial_driver.

These changes were missed somehow in commits 00a0d0d65b61 ("tty: remove
filp from the USB tty ioctls") and 60b33c133ca0b ("tiocmget: kill off
the passing of the struct file")

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: mct_u232: added _ioctl, _msr_to_icount and _get_icount functions

2011-02-04T19:42:51+00:00

Added mct_u232_ioctl (implements TIOCMIWAIT command),
mct_u232_get_icount (implements TIOCGICOUNT command) and
mct_u232_msr_to_icount functions. MCT U232 P9 is one of a few usb to
serail adapters which converts USB +/-5v voltage levels to COM +/-15
voltages. So it can also power COM interfaced devices. This makes it
very usable for legacy COM interfaced data-acquisition hardware. I
tested new implementation with AWARE Electronics RM-60 radiation meter,
which sends pulse via RNG COM line whenever new particle is registered.

USB: mct_u232: fix broken close

2010-10-22T17:22:19+00:00

Fix regression introduced by commit
f26788da3b342099d2b02d99ba1cb7f154d6ef7b (USB: serial: refactor generic
close) which broke driver close().

This driver uses non-standard semantics for the read urb which makes the
generic close function fail to kill it (the read urb is actually an
interrupt urb and therefore bulk_in size is zero).

USB: serial: refactor generic close

2010-05-20T20:21:33+00:00

Export usb_serial_generic_close so that drivers can easily kill the read
and write urb and make sure that the write fifo is reset.
