staging: tidspbridge: Clean up error-handling code
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/)
// <smpl>
@@
expression ret;
expression x,e1,e2,e3;
@@
ret = 0
... when != ret = e1
*x = \(kmalloc\|kcalloc\|kzalloc\)(...)
... when != ret = e2
if (x == NULL) { ... when != ret = e3
return ret;
}
// </smpl>
