1d0e413791 gpib: Add ines_pci_xl_interface
Add new interface initialisation struct for 72130 based boards.

It is basically the same as the ines_pci_interface apart from the
name, attach and line_status fields.

1b2bfb7ac2 gpib: Don't use extended registers
When the chip type is 72310 then avoid accessing extended registers
Apart from the BSR the 72310 supports only the standard NEC u7210
registers.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

e6ab504633 staging: gpib: Destage gpib
Move the gpib drivers out of staging and into the "real" part of the
kernel.  This entails:

 - Remove the gpib Kconfig menu and Makefile build rule from staging.
 - Remove gpib/uapi from the header file search path in subdir-ccflags
   of the gpib Makefile
 - move the gpib/uapi files to include/uapi/linux
 - Move the gpib tree out of staging to drivers.
 - Remove the word "Linux" from the gpib Kconfig file.
 - Add the gpib Kconfig menu and Makefile build rule to drivers
