From 72f2b0b2185099dce354c805009f591dda3ab73d Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Mon, 30 Jan 2023 22:10:50 +0100 Subject: drivers/block: Move PARIDE protocol modules to drivers/ata/pata_parport Move PARIDE protocol modules out of drivers/block into drivers/ata/pata_parport and update the CONFIG_ symbol names to PATA_PARPORT. [Damien] The pata_parport driver file itsef is also moved together with the protocol modules in drivers/ata/pata_parport.
