Subject: [PATCH V2 4/4] spmi: pmic-arb: Remove checking opc value not less than 0
Date: Mon, 10 Jul 2017 18:35:26 +0530	[thread overview]
Message-ID: <1499691926-16030-5-git-send-email-kgunda@codeaurora.org> (raw)
In-Reply-To: <1499691926-16030-1-git-send-email-kgunda@codeaurora.org>

From: Fenglin Wu <fenglinw@codeaurora.org>

The opc parameter in pmic_arb_write_cmd() function is defined with type
u8 and it's always greater than or equal to 0. Checking that it's not
less than 0 is redundant and it can cause a forbidden warning during
compilation. Remove the check.
