From 62d494ca2773563e333e670cd18378705dad32d4 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 6 Nov 2015 12:22:08 +0100 Subject: [PATCH] mmc: mediatek: Preinitialize delay_phase in get_best_delay() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit drivers/mmc/host/mtk-sd.c: In function ‘get_best_delay’: drivers/mmc/host/mtk-sd.c:1284: warning: ‘delay_phase.start’ is used uninitialized in this function drivers/mmc/host/mtk-sd.c:1284: warning: ‘delay_phase.maxlen’ is used uninitialized in this function If delay is zero, these fields are indeed not initialized. Let the compiler preinitialize the whole struct to fix this.
