From 2c3e0262e0cb5395fe02cdf27c229ee7414ab0c0 Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Fri, 23 Jun 2006 02:04:51 -0700 Subject: [PATCH] m68k: completely initialize hw_regs_t in ide_setup_ports ide_setup_ports does not completely initialize the hw_regs_t structure which can cause random failures, as the structure is often on the stack. None of the callers expect a partially initialized structure, i.e. none of them do any setup of their own before calling ide_setup_ports().
