commit ea41020b9018e31c2ea7e9d89021e3e6d7470883 upstream.

The EEPROM on my board has a vendor specific entry of type 0x41. When
stumbling upon that, this driver hangs in an endless loop.

Fix it by keep incrementing the offset on unknown entries, so the loop
will eventually stop.

commit 5b6b6fc491899d583eaa75344e094796ae9b530b upstream.

Fix several instances of error paths in which we call
__nvmem_device_put() - which may end up freeing the underlying memory
and other resources - and then keep on using the nvmem structure. Always
put the reference to the nvmem device as the last step before returning
the error code.

Buffer size used in dma allocation and memcpy is wrong.
It can lead to undersized DMA buffer access and possible
memory corruption. use correct buffer size in dma_alloc_coherent
and memcpy.

Avoid getting error messages at startup like the following on i.MX6ULL:

nvmem imx-ocotp0: cell mac-addr raw len 6 unaligned to nvmem word size 4
nvmem imx-ocotp0: cell mac-addr raw len 6 unaligned to nvmem word size 4

This shouldn't cause any functional change as this alignment would
otherwise be done in nvmem_cell_info_to_nvmem_cell_entry_nodup().

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.

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 *".

If nvmem_add_one_cell() failed, the ownership of "child" (or "info.np"),
thus its OF reference, is not passed further and function should clean
up by putting the reference it got via earlier of_node_get().  Note that
this is independent of references obtained via for_each_child_of_node()
loop.
