Subject: [PATCH v2 11/28] drivers: Add generic helper to match any device
Date: Fri, 14 Jun 2019 18:54:06 +0100 [thread overview]
Message-ID: <1560534863-15115-12-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1560534863-15115-1-git-send-email-suzuki.poulose@arm.com>
Add a generic helper to match any/all devices. This will be
used for providing {bus/driver/class}_find_next_device()
