Subject: [PATCH] i2c: core: do not use logical device when creating irq domain
Date: Wed, 1 Jul 2020 10:23:18 +0200 [thread overview]
Message-ID: <20200701082318.11174-1-wsa+renesas@sang-engineering.com> (raw)
Let's rather use its physical parent device to give proper namings and
connections in debugfs.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

This turns the name from "unknown-1" to ":soc:i2c@e6540000" in debugfs
for my use case.
@Benjamin: I am not aware of any other side effects or regression
possibilites. Do you see any?
