Subject: [PATCH 1/1] drivers/rtc/rtc-bq32k.c: remove redundant check
Date: Wed, 08 Jul 2015 12:26:47 +0530	[thread overview]
Message-ID: <1436338607-43389-1-git-send-email-maninder1.s@samsung.com> (raw)

removing below static analysis error:-
(error) Possible null pointer dereference: client

if (!i2c_check_functionality(client->adapter, I2C_FUNC_I2C))
							^^^^^^^
Error comes beacause client is dereferenced before NULL check.
So probabily NULL this check is not required.
