Subject: [PATCH 10/10] fpga: fpga-mgr: altera-pr-ip: Simplify registration
Date: Sat,  3 Oct 2020 22:14:23 -0700	[thread overview]
Message-ID: <20201004051423.75879-11-mdf@kernel.org> (raw)
In-Reply-To: <20201004051423.75879-1-mdf@kernel.org>

Simplify registration using new devm_fpga_mgr_register() API.
Remove the now obsolete altera_pr_unregister() function.

Signed-off-by: Moritz Fischer <mdf@kernel.org>

We should take another look at this, IIRC correctly the point of
splitting this up into a separate driver was to make it useable by a
different (pci?) driver later on.

It doesn't seem like this happened, and I think we should just make this
a platform driver?
