Subject: [RFC PATCH 23/35] sparc/PCI: Change PCIBIOS_SUCCESSFUL to 0
Date:   Mon, 13 Jul 2020 14:22:35 +0200
Message-Id: <20200713122247.10985-24-refactormyself@gmail.com>
In-Reply-To: <20200713122247.10985-1-refactormyself@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In reference to the PCI spec (Chapter 2), PCIBIOS* is an x86 concept.
Their scope should be limited within arch/x86.

Change all PCIBIOS_SUCCESSFUL to 0
