Subject: [RFC v1 PATCH 3/3] driver: update all the code that use soc_device_match
Date: Mon, 19 Apr 2021 12:27:22 +0800
Message-ID: <20210419042722.27554-4-alice.guo@oss.nxp.com> (raw)
In-Reply-To: <20210419042722.27554-1-alice.guo@oss.nxp.com>

From: Alice Guo <alice.guo@nxp.com>

Update all the code that use soc_device_match because add support for
soc_device_match returning -EPROBE_DEFER.

Signed-off-by: Alice Guo <alice.guo@nxp.com>
