Merge git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac
Pull EDAC fixes from Mauro Carvalho Chehab: "One EDAC core fix, and a few driver fixes (i7300, i9275x, i7core)." * git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac: i7core_edac: fix panic when accessing sysfs files i7300_edac: Fix error flag testing edac: Fix the dimm filling for csrows-based layouts i82975x_edac: Fix dimm label initialization
