[ Upstream commit aac6c0f90799d66b8989be1e056408f33fd99fe6 ]
The xilinx dma driver uses the consistent allocations, so for correct
operation also set the DMA mask for coherent APIs. It fixes the below
kernel crash with dmatest client when DMA IP is configured with 64-bit
address width and linux is booted from high (>4GB) memory.

If kobject_init_and_add return with error, then the cleanup of kobject
is needed because memory may be allocated in kobject_init_and_add
without freeing.
And the place of cleanup_dev_kobject should use kobject_put to free the
memory associated with the kobject. As the section "Kobject removal" of
"Documentation/core-api/kobject.rst" says, kobject_del() just makes the
kobject "invisible", but it is not cleaned up. And no more cleanup will
do after cleanup_dev_kobject, so kobject_put is needed here.

[ Upstream commit dbc6e7d44a514f231a64d9d5676e001b660b6448 ]
In nilfs_##name##_attr_release, kobj->parent should not be referenced
because it is a NULL pointer. The release() method of kobject is always
called in kobject_put(kobj), in the implementation of kobject_put(), the
kobj->parent will be assigned as NULL before call the release() method.
So just use kobj to get the subgroups, which is more efficient and can fix
a NULL pointer reference problem.
