This patch removes the auerswald USB driver from the linux kernel 2.6.26. This driver was included into the kernel mainly to connect to the ISDN framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile and moving ISDN support, this connection was never realized, and the only use of this driver was for device configuration. In the age of DSL, the demand of ISDN support is getting very low. Meanwhile, with the advent of libusb, an userspace driver was done for the device configuration which works fine for linux and mac. (Thanks to the libusb developers!). The userspace driver is downloadable from the auerswald web site. So this driver is obsolete now and has to be removed. Many thanks to all developers which helped me to bring this driver up and working. Signed-off-by: Wolfgang Muees <wolfgang@iksw-muees.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Ioctl Numbers

|
|
If you are adding new ioctl's to the kernel, you should use the _IO
|
|
macros defined in <linux/ioctl.h>:
|
|
|
|
_IO an ioctl with no parameters
|
|
_IOW an ioctl with write parameters (copy_from_user)
|
|
_IOR an ioctl with read parameters (copy_to_user)
|
|
_IOWR an ioctl with both write and read parameters.
|
|
|
|
'Write' and 'read' are from the user's point of view, just like the
|
|
system calls 'write' and 'read'. For example, a SET_FOO ioctl would
|
|
be _IOW, although the kernel would actually read data from user space;
|
|
a GET_FOO ioctl would be _IOR, although the kernel would actually write
|
|
data to user space.
|
|
|
|
The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
|
|
or number from the table below. Because of the large number of drivers,
|
|
many drivers share a partial letter with other drivers.
|
|
|
|
If you are writing a driver for a new device and need a letter, pick an
|
|
unused block with enough room for expansion: 32 to 256 ioctl commands.
|
|
You can register the block by patching this file and submitting the
|
|
patch to Linus Torvalds. Or you can e-mail me at <mec@shout.net> and
|
|
I'll register one for you.
|
|
|
|
The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
|
|
to distinguish ioctls from each other. The third argument to _IOW,
|
|
_IOR, or _IOWR is the type of the data going into the kernel or coming
|
|
out of the kernel (e.g. 'int' or 'struct foo'). NOTE! Do NOT use
|
|
sizeof(arg) as the third argument as this results in your ioctl thinking
|
|
it passes an argument of type size_t.
|
|
|
|
Some devices use their major number as the identifier; this is OK, as
|
|
long as it is unique. Some devices are irregular and don't follow any
|
|
convention at all.
|
|
|
|
Following this convention is good because:
|
|
|
|
(1) Keeping the ioctl's globally unique helps error checking:
|
|
if a program calls an ioctl on the wrong device, it will get an
|
|
error rather than some unexpected behaviour.
|
|
|
|
(2) The 'strace' build procedure automatically finds ioctl numbers
|
|
defined with _IO, _IOW, _IOR, or _IOWR.
|
|
|
|
(3) 'strace' can decode numbers back into useful names when the
|
|
numbers are unique.
|
|
|
|
(4) People looking for ioctls can grep for them more easily when
|
|
this convention is used to define the ioctl numbers.
|
|
|
|
(5) When following the convention, the driver code can use generic
|
|
code to copy the parameters between user and kernel space.
|
|
|
|
This table lists ioctls visible from user land for Linux/i386. It contains
|
|
most drivers up to 2.3.14, but I know I am missing some.
