From 48018943eb906d81e48f40675c17b92abfeafcf1 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 13 Aug 2014 11:42:46 +0100 Subject: mfd: wm5102: Mark register write sequencer control 3 readable During init the core checks if the wm5102 has finished starting by reading register 0x19 and looking at the value. This read always fails since this is not a readable register, mark it as being one. While we're at it provide a constant for the register name (as supplied by Charles Keepax).
