Subject: [PATCH 3/6] of: make struct property _flags field configurable
Date: Thu, 5 Oct 2017 14:44:19 -0500 [thread overview]
Message-ID: <20171005194422.26224-4-robh@kernel.org> (raw)
In-Reply-To: <20171005194422.26224-1-robh@kernel.org>
Only Sparc and CONFIG_OF_DYNAMIC use the struct property._flags field,
so make it conditional shrinking struct property a bit.
