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).
Fixes: b745c0794e2f ("clk: keystone: Add sci-clk driver support")
Depends-on: 96488c09b0f4 ("clk: keystone: sci-clk: cut down the clock name length")
