Subject: [PATCH 26/23] floppy: cleanup: get rid of current_reqD in favor of current_drive
Date:   Fri, 10 Apr 2020 12:19:03 +0200
Message-Id: <20200410101904.14652-2-w@1wt.eu>
In-Reply-To: <20200410101904.14652-1-w@1wt.eu>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This macro equals -1 and is used as an alternative for current_drive when
calling reschedule_timeout(), which in turn needs to remap it. This only
adds obfuscation, let's simply use current_drive.
