Subject: [PATCH] Input: synaptics-rmi4 - remove the useless unsigned variable compared with zero
Date: Mon, 23 Nov 2020 14:37:08 +0800	[thread overview]
Message-ID: <1606113428-21462-1-git-send-email-kaixuxia@tencent.com> (raw)

From: Kaixu Xia <kaixuxia@tencent.com>

It is always true that the value of unsigned variable size_presence_reg
greater than or equal to zero, so compared with zero is unnecessary.
Remove it.
