spi: dw-pci: fix bug when regs left uninitialized 2014-10-05T20:41:01+00:00 Andy Shevchenko andriy.shevchenko@linux.intel.com 2014-08-27T13:21:12+00:00 a3e4b7577cc0de761fff82ae3eff6507307c0d1c commit c9d5d6fe168fd45a4dfdd0116affe708789b4702 upstream. 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.
