Subject: [PATCH v3 13/20] coresight: remove multiple init calls from replicator driver
Date: Fri, 17 Jul 2020 13:45:29 +0800	[thread overview]
Message-ID: <20200717054536.7052-14-tingwei@codeaurora.org> (raw)
In-Reply-To: <20200717054536.7052-1-tingwei@codeaurora.org>

From: Mian Yousaf Kaukab <ykaukab@suse.de>

Dynamic-replicator uses module_amba_driver to register. Whereas
static-replicator uses builtin_platform_driver. Combine these init
calls into a single module_init/exit pair in preparation to make the
driver modular.
