Subject: [PATCH v2 7/9] frame: Only include valid definitions depending on source file type
Date: Thu, 30 Jul 2020 10:46:50 +0100	[thread overview]
Message-ID: <20200730094652.28297-8-jthierry@redhat.com> (raw)
In-Reply-To: <20200730094652.28297-1-jthierry@redhat.com>

Header include/linux/frame.h contains both C and assembly definition that
are visible regardless of the file including them.

Place definition under conditional __ASSEMBLY__.
