Subject: [RFC PATCH 07/35] PCI: Change PCIBIOS_SUCCESSFUL to 0
Date: Mon, 13 Jul 2020 14:22:19 +0200 [thread overview]
Message-ID: <20200713122247.10985-8-refactormyself@gmail.com> (raw)
In-Reply-To: <20200713122247.10985-1-refactormyself@gmail.com>
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
