Subject: [PATCH v3 04/18] MIPS: PCI: Inline pcibios_assign_all_busses
Date: Wed, 5 Oct 2016 18:18:10 +0100	[thread overview]
Message-ID: <20161005171824.18014-5-paul.burton@imgtec.com> (raw)
In-Reply-To: <20161005171824.18014-1-paul.burton@imgtec.com>

The MIPS implementation of pcibios_assign_all_busses trivially returns
1. Implement it as a static function in asm/pci.h such that the compiler
can inline it & optimise out never-taken paths.
