From 2129e56e95f877c71989e7d0391de47f3907a261 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 18 Oct 2019 10:23:49 +0100 Subject: [PATCH] mfd: cs5535-mfd: Remove mfd_cell->id hack The current implementation abuses the platform 'id' mfd_cell member to index into the correct resources entry. Seeing as enough resource slots are already available, let's just loop through all available bars and allocate them to their appropriate slot, even if they happen to be zero.
