Subject: [PATCH i2c-next 1/1] i2c: mlxcpld: Add callback to notify probing completion
Date: Wed, 13 Jul 2022 12:11:36 +0300 [thread overview]
Message-ID: <20220713091136.734-1-vadimp@nvidia.com> (raw)
Add notification to inform caller that driver probing has been
completed. It allows to user, invoked platform device registration for
"i2c-mlxcpld" driver, to be notified that bus adapter is available, and
thus some devices could be connected to this bus.
