Subject: [PATCH 08/10] floppy: cleanup: expand macro DRWE
Date: Mon, 24 Feb 2020 22:23:50 +0100	[thread overview]
Message-ID: <20200224212352.8640-9-w@1wt.eu> (raw)
In-Reply-To: <20200224212352.8640-1-w@1wt.eu>

This macro doesn't bring much value and only slightly obfuscates the
code by silently using global variable "current_drive", let's expand it.
