Patch 1 is a bug fix
Patches 2-4 replace custom debug with dev_dbg as well as
using dev_xxx for pr_xxx where feasible.
Patch 5 Fixes the agilent_usb module description
Patch 6 Addresses a checkpatch CHECK for mutex comment
Patch 7 Changes dev_xxx for pr_xxx in the agilent PCI driver
Patch 8 Corrects some errors in Kconfig
Patch 9-11 are code cleanups
Patch 12 corrects some GPIB behaviour
Changes in v3
Incorporate the lpvo patch 5 into patch 2
Remove commented out console messages in patch 4
Add a separate patch for module description -> Patch 5
Add a separate patch for mutex comment -> Patch 6
Change "spelling error" to "typo" in commit message in patch 8 (was 7)
Clarfiy commit message in patch 11 (was patch 10)
Add a fixes tag to patch 12 (was 11)
Changes in v2
Add staging: gpib: prefix to subject lines
-Patch 1 Use kmalloc_array, remove blanks in commit message and add Fixes tag
-Patch 3 Delete commented out code
-Patch 7 Fix Fixes tag
-Patch 8 Split into 3 patches 8,9 & 10
-Patch 9 -> 11 Clarify commit message, delete blank line and add defines
for max primary and secondary addresses.

Replace GPIB_DPRINTK with dev_dbg
Replace pr_xxx with dev_xxx wherever possible
Use previously initialized usb_device pointer
for usb_get_dev() and usb_put_dev().

Remove bcm2837 table as the only difference is GPIO14 and GPIO15
which are not used with the current pin maps.

Re-order the tables so that the bcm27xx table is used first
as these devices are more popular and numerous than the older ones.
This is slightly more efficient for the later pi3 and subsequent models
but should not be noticable in practice for all users.

GPIB secondary addresses can be between 0 and 31 inclusive
unlike primary addresses where address 31 is not a valid device
address. When 31 is used as a primary talk address it
forms the UNT (Untalk) command and when used as a listener address it
forms the UNL (Unlisten) commmand.
The library was incorrectly not allowing a secondary address
with a value of 31 to be used.
