Subject: [PATCH 1/2] rtc: class: add debug message when registration fails
Date: Mon, 19 Aug 2019 00:00:40 +0200 [thread overview]
Message-ID: <20190818220041.17833-1-alexandre.belloni@bootlin.com> (raw)
Add a message when __rtc_register_device fails because rtc->ops is NULL.
This may only happen when developing a new driver so use dev_dbg to avoid
compiling it in by default.
