RDMA/bng_re: Unwind bng_re_dev_init properly
...
Fix below smatch warning:
drivers/infiniband/hw/bng_re/bng_dev.c:270
bng_re_dev_init() warn: missing unwind goto?
Current bng_re_dev_init function is not having clear unwinding code.
So, added proper unwinding with ladder.

RDMA/bng_re: Remove unnessary validity checks
...
Fix below smatch warning:
drivers/infiniband/hw/bng_re/bng_dev.c:113
bng_re_net_ring_free() warn: variable dereferenced before check 'rdev'

current driver has unnessary validity checks. So, removing these
unnessary validity checks.

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.

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 *".
