Subject: [PATCH] drivers: i2c: remove dead code in davinci_i2c_probe
Date: Mon,  6 Mar 2023 10:45:23 +0800	[thread overview]
Message-ID: <20230306024523.248216-1-dzm91@hust.edu.cn> (raw)

From the comment of platform_get_irq, it only returns non-zero IRQ
number and negative error number, other than zero.

Fix this by removing the if condition.
