Driver returns -EOPNOTSUPPORTED on unsupported parameters case in set

code mismatch, the ioctls from userspace fail. Resolve the issue by
passing -ENOTSUPP during unsupported case.

In the previous commit referenced below, I had to split
the short fops handling into different proxy fops. This
necessitated knowing out-of-band whether or not the ops
are short or full, when attempting to convert from fops
to allocated fsdata.

Unfortunately, I only converted full_proxy_open() which
is used for the new full_proxy_open_regular() and
full_proxy_open_short(), but forgot about the call in
open_proxy_open(), used for debugfs_create_file_unsafe().

Fix that, it never has short fops.

mite_dma_disarm).

Remove all of the unused functions in the gpib mite.c and .h files as
they aren't needed and cause the compiler to be confused.

Commit 79d2e1919a27 ("staging: gpib: fix Makefiles") uses the corresponding
config symbols to let Makefiles include the driver sources appropriately in
the kernel build.

Unfortunately, the Makefile in the tnt4882 directory refers to the
non-existing config GPIB_TNT4882. The actual config name for this driver is
GPIB_NI_PCI_ISA, as can be observed in the gpib Makefile.

Probably, this is caused by the subtle differences between the config
names, directory names and file names in ./drivers/staging/gpib/, where
often config names and directory names are identical or at least close in
naming, but in this case, it is not.

Change the reference in the tnt4882 Makefile from the non-existing config
GPIB_TNT4882 to the existing config GPIB_NI_PCI_ISA.

During fuzz testing, the following warning was discovered:

different return values (15 and 11) from vsnprintf("%*pbl

test:keyward is WARNING in kvasprintf
WARNING: CPU: 55 PID: 1168477 at lib/kasprintf.c:30 kvasprintf+0x121/0x130

entry_SYSCALL_64_after_hwframe+0x78/0xe2

The call trace shows that kvasprintf() reported this warning during the
printing of core_siblings_list. kvasprintf() has several steps:

(1) First, calculate the length of the resulting formatted string.

(2) Allocate a buffer based on the returned length.

(3) Then, perform the actual string formatting.

(4) Check whether the lengths of the formatted strings returned in
steps (1) and (2) are consistent.

If the core_cpumask is modified between steps (1) and (3), the lengths
obtained in these two steps may not match. Indeed our test includes cpu
hotplugging, which should modify core_cpumask while printing.

To fix this issue, cache the cpumask into a temporary variable before
calling cpumap_print_{list, cpumask}_to_buf(), to keep it unchanged
during the printing process.
