Subject: [PATCH -next] drm/ch7006: Use match_string() helper to simplify the code
Date: Fri, 10 Jan 2020 17:19:26 +0800	[thread overview]
Message-ID: <20200110091926.48380-1-yuehaibing@huawei.com> (raw)

match_string() returns the array index of a matching string.
Use it instead of the open-coded implementation.
