Subject: [PATCH 17/23] floppy: cleanup: make fdc_configure() not rely on current_fdc anymore
Date: Tue, 31 Mar 2020 11:40:48 +0200 [thread overview]
Message-ID: <20200331094054.24441-18-w@1wt.eu> (raw)
In-Reply-To: <20200331094054.24441-1-w@1wt.eu>
Now the fdc is passed in argument so that the function does not
use current_fdc anymore.
