Message-Id: <20230403094113.6056-2-tsbogend@alpha.franken.de>
Date: Mon, 3 Apr 2023 11:41:11 +0200
From: Thomas Bogendoerfer <tsbogend@...ha.franken.de>
To: linux-mips@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 2/3] MIPS: Remove no longer used ide.h
There are only three drivers left using ide.h, which are all m68k only.
