Subject: [PATCH 2/7] Revert "serial: uartps: Use the same dynamic major number for all ports"
Date: Fri, 3 Apr 2020 11:24:31 +0200 [thread overview]
Message-ID: <14a565fc1e14a5ec6cc6a6710deb878ae8305f22.1585905873.git.michal.simek@xilinx.com> (raw)
In-Reply-To: <cover.1585905873.git.michal.simek@xilinx.com>
This reverts commit ab262666018de6f4e206b021386b93ed0c164316.
As Johan says, this driver needs a lot more work and these changes are
only going in the wrong direction:
