From 7e5dc1f7004832f797999dfb3498a68a6c16ef73 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Tue, 1 Mar 2011 13:55:07 -0800 Subject: w1: Silence ds1wm warnings related to mfd_get_cell changes mfd_get_cell returns a const, so change the ds1wm client to store a const mfd cell. This silences type mismatch warnings. Since we're guaranteed to have the mfd_cell, we can also simplify the code a bit to get rid of a temporary variable and NULL check.
