Subject: [PATCH 5.6 226/254] clk: ingenic/jz4770: Exit with error if CGU init failed
From: Paul Cercueil <paul@...pouillou.net>
commit c067b46d731a764fc46ecc466c2967088c97089e upstream.
Exit jz4770_cgu_init() if the 'cgu' pointer we get is NULL, since the
pointer is passed as argument to functions later on.
Fixes: 7a01c19007ad ("clk: Add Ingenic jz4770 CGU driver")
