Subject: [PATCH] i2c: drivers: Remove superfluous error message
Date:   Mon,  4 May 2020 17:14:06 +0530
Message-Id: <20200504114408.9128-1-aishwaryarj100@gmail.com>
In-Reply-To: <20200503120847.13528-1-aishwaryarj100@gmail.com>
References: <20200503120847.13528-1-aishwaryarj100@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The function platform_get_irq can log an error by itself.
This omit a redundant message for exception handling in the
calling function.

Suggested by Coccinelle.
