Subject: [PATCH 3/5] Input: hilkbd - Add casts to HP9000/300 I/O accessors
Date:   Mon,  2 Jul 2018 15:35:30 +0200
Message-Id: <20180702133532.5412-4-geert@linux-m68k.org>
In-Reply-To: <20180702133532.5412-1-geert@linux-m68k.org>
References: <20180702133532.5412-1-geert@linux-m68k.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Internally, hilkbd uses "unsigned long" I/O addresses everywhere.
This works fine as:
  - On PA-RISC, hilkbd uses the gsc_{read,write}b() I/O accessors, which
    take "unsigned long" addresses,
  - On m68k, hilkbd uses {read,write}b(), which are currently mapped to
    {in,out}_8(), and convert the passed addresses to pointers
    internally.

However, the asm-generic version of {read,write}b() does not perform
such conversions, and requires passing pointers instead.  Hence add
casts to prepare for switching m68k to the asm-generic version.

This is a dependency for "m68k/io: Switch mmu variant to
<asm-generic/io.h>".
