From e962cd9cf9cfb1f5db6bbad6a6470e5ccf56e290 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Wed, 16 Oct 2019 15:45:38 +0100 Subject: parport: do not check portlist when using device-model We do not need to maintain a list of ports when we are using the device-model. The base layer is going to maintain the list for us and we can get the list of ports just using bus_for_each_dev().
