Hi,

I recently updated from 2.6.0-test4 to 2.6.3 and noticed that my pt_drv
won't work any more. It did not load, telling me something like
missing symbol: kdev_t_to_nr

I investigated and found the problem:
the inline function kdev_t_to_nr does not exist any longer, I think it's
depr. due to the kdev device changes in 2.6.3 (2.6.2?).

ptdrv.c:
255: int minor = MINOR(kdev_t_to_nr(ip->i_rdev));

Anyway, I could not figure out what function might be it's successor, so
I simply removed the function call, leading to:

ptdrv.c:
225: int minor = MINOR(ip->i_rdev);

All kdev_t.h functions existing in 2.6.3 did only bad stuff to the
numbers so think this might be correct.

I just removed it, as it works for me (and should logically, reviewing
how the MINOR inline works now). I could not test it with more than one
scanner device, so it might still be false.

Anyone out there who can proof whether this is OK like this?

Attached the changed patch...

cu,
~  Lars

Hmm,

I don't think that this patch is necessary anymore. The latest driver
is contained in the sane-backends package. The backend is called
plustek_pp can can either be used completely from userspace or if
you want to as kernel-module (including all the patches for 2.6
kernel, except devfs support).

Ciao,
  Gerhard
