Subject: [PATCH 1/6] Revert "MIPS: ralink: don't define PC_IOBASE but increase IO_SPACE_LIMIT"
Date: Fri, 24 Sep 2021 23:11:34 +0200	[thread overview]
Message-ID: <20210924211139.3477-2-sergio.paracuellos@gmail.com> (raw)
In-Reply-To: <20210924211139.3477-1-sergio.paracuellos@gmail.com>

This reverts commit 159697474db41732ef3b6c2e8d9395f09d1f659e.

There is no real need to increase IO_SPACE_LIMIT if PCI_IOBASE
is properly set to 'mips_io_port_base'. Hence revert this commit
first before doing anything else.
