From 0e5fca8106199f5c680bb93e75c16381c4c256ce Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Thu, 29 Nov 2012 08:48:26 +0000 Subject: [PATCH] mfd: tps65910: Remove unused data The 'io_mutex' is not used anywhere. The regmap API supports the mutex internally, so no additional mutex is required. And 'domain' private data is unnecessary because the irq domain is already registered by using regmap_add_irq_chip().
