clk: clocking-wizard: check return value of devm_kasprintf()
[ Upstream commit b1356ed1a4461de06dfdc02bf549c3e8750162e5 ]
devm_kasprintf() returns a pointer to dynamically allocated memory.
Pointer could be NULL in case allocation fails. Check pointer validity.
Identified with coccinelle (kmerr.cocci script).
