Subject: [PATCH 3/3] staging: mt7621-pci: set end limit for 'ioport_resource'
Date: Sat, 7 Aug 2021 09:24:09 +0200 [thread overview]
Message-ID: <20210807072409.9018-4-sergio.paracuellos@gmail.com> (raw)
In-Reply-To: <20210807072409.9018-1-sergio.paracuellos@gmail.com>
We have increase IO_SPACE_LIMIT for ralink platform to get PCI IO resources
properly handled using PCI core APIs. To align those changes with driver
code we have to set 'ioport_resource' end limit to IO_SPACE_LIMIT to avoid
errors.
