Subject: [PATCH v2 1/2] clk: ingenic/jz4770: Exit with error if CGU init failed
Date: Thu, 13 Feb 2020 13:19:51 -0300	[thread overview]
Message-ID: <20200213161952.37460-1-paul@crapouillou.net> (raw)

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")
Cc: stable@vger.kernel.org
Signed-off-by: Paul Cercueil <paul@crapouillou.net>
