Subject: [PATCH v1] mfd:mcp-core.c : Remove redundant driver match function
Date: Sun, 19 Mar 2023 12:01:49 +0800 [thread overview]
Message-ID: <20230319040149.216919-1-sensor1010@163.com> (raw)
If there is no driver_match function, the driver core assumes that each
candidate pair (driver, device)matches, see driver_match_device()
