This should fix the problem of comedi drivers showing up on arches that
can not support the comedi subsystem (like s390).

1. The memory into which we copy 'u1@u2' needs space for u1, @,
u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument. So use a
temporary variable to pass to it, so we pass the original
value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
since we later kstrdup it.
I am about to send out an LTP testcase for this driver, but
in addition the correctness of the hashing can be verified as
follows:

#include <stdlib.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
char in[41], out[20];
unsigned int v;
int i, ret;
ret = read(STDIN_FILENO, in, 40);
if (ret != 40)
exit(1);
in[40] = '\0';
for (i = 0; i < 20; i++) {
sscanf(&in[2*i], "%02x", &v);
out[i] = v;
}
write(STDOUT_FILENO, out, 20);
}

prepare_discard_fn() was being called in a place where memory allocation
was effectively impossible. This makes it inappropriate for all but
the most trivial translations of Linux's DISCARD operation to the block
command set. Additionally adding a payload there makes the ownership
of the bio backing unclear as it's now allocated by the device driver
and not the submitter as usual.
It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether
the queue supports discard operations or not. blkdev_issue_discard now
allocates a one-page, sector-length payload which is the right thing
for the common ATA and SCSI implementations.
The mtd implementation of prepare_discard_fn() is replaced with simply
checking for the request being a discard.
Largely based on a previous patch from Matthew Wilcox <matthew@wil.cx>
which did the prepare_discard_fn but not the different payload allocation
yet.

Compatibility code is not allowed upstream. While this could
eventually be useful by out-of-tree compilation, directly from
http://linuxtv.org/hg/v4l-dvb tree, the compatibility code is at
the wrong place. In a matter of fact, it is not needed at all, since
compat.h already handles such things.
