In the first hunk, 0 is returned on memory allocation failure, even though
other failures return -ENOMEM or other similar values.
In the second hunk, there was error handling code that returned without
freeing psz_path_name.
A simplified version of the semantic match that finds the first problem is as
follows: (http://coccinelle.lip6.fr/)

This driver uses ioremap on regular memory to get an uncached mapping,
which causes problems on ARMv6 and higher due to aliasing with the
cached linar kernel mapping.
Make sure this gets fixed before the driver graduates from staging.

The cfg_get_dev_object function is only used in one place and because of
its simplicity, it can be removed.
The parameter *value can be left uninitialized if the strcmp() returns a
nonzero value, so in the function dev_remove_device(), the hdev_obj could
be used uninitialized and could be dereferenced in dev_destroy_device().
This patch fixes this issue, and also removes the dev_obj pointer which
is not used.
