Subject: [PATCH 2/2] i2c: smbus: Use device_ functions instead of of_
Date: Thu, 16 Dec 2021 18:43:22 +0530	[thread overview]
Message-ID: <1639660402-31207-3-git-send-email-akhilrajeev@nvidia.com> (raw)
In-Reply-To: <1639660402-31207-1-git-send-email-akhilrajeev@nvidia.com>

Change of_ functions to device_ for firmware agnostic usage.
This allows to have smbus_alert interrupt without any changes
in the controller drivers using ACPI table.
