From c9d5d6fe168fd45a4dfdd0116affe708789b4702 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 27 Aug 2014 16:21:12 +0300 Subject: [PATCH] spi: dw-pci: fix bug when regs left uninitialized The commit 04f421e7 "spi: dw: use managed resources" changes drivers to use managed functions, but seems wasn't properly tested in PCI case. The regs field of struct dw_spi left uninitialized. Thus, kernel crashes when tries to access to the SPI controller registers. This patch fixes the issue.
