Subject: [PATCH 19/23] floppy: cleanup: make check_wp() not rely on current_{fdc,drive} anymore
Date: Tue, 31 Mar 2020 11:40:50 +0200 [thread overview]
Message-ID: <20200331094054.24441-20-w@1wt.eu> (raw)
In-Reply-To: <20200331094054.24441-1-w@1wt.eu>
Now the fdc and drive are passed in argument so that the function does
not use current_fdc nor current_drive anymore.
