From d7fe833f3fc9a02806c96dd28f48e5e28c8484a8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 5 Jun 2014 23:14:39 +0200 Subject: mmc: mvsdio: avoid compiler warning gcc correctly points out that hw_state can be used uninitially in the mvsd_setup_data() function. This rearranges the function to ensure it always contains a proper value.
