Claudiu Beznea fd9324fa4d clk: keystone: sci-clk: check return value of kasprintf() ...

[ Upstream commit b73ed981da6d25c921aaefa7ca3df85bbd85b7fc ]

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).

Depends-on: 96488c09b0 ("clk: keystone: sci-clk: cut down the clock name length")
