Subject: [PATCH 2/5] staging: erofs: localize erofs_workgroup_get
Date: Wed, 16 Jan 2019 16:59:53 +0800	[thread overview]
Message-ID: <20190116085956.21004-2-gaoxiang25@huawei.com> (raw)
In-Reply-To: <20190116085956.21004-1-gaoxiang25@huawei.com>

Staticize erofs_workgroup_get since no external user
out of utils.c directly calls erofs_workgroup_get.

Signed-off-by: Gao Xiang <gaoxiang25@huawei.com>
