Subject: [PATCH v1 1/3] arm64: module: move find_section to header
Date: Thu, 25 Aug 2022 11:20:23 +0100	[thread overview]
Message-ID: <20220825102025.53916-2-joey.gouly@arm.com> (raw)
In-Reply-To: <20220825102025.53916-1-joey.gouly@arm.com>

Move it to the header so that the implementation can be shared
by the alternatives code.
