Claudiu Beznea 67684f0688 clk: keystone: sci-clk: check return value of kasprintf() 
[ Upstream commit b73ed981da ]

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: b745c0794e ("clk: keystone: Add sci-clk driver support")
Depends-on: 96488c09b0 ("clk: keystone: sci-clk: cut down the clock name length")
