Subject: powerpc/powernv: Remove unused file
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2f6cf7944833bf9c63b945799b460988aec30040;p=deliverable%2Flinux.git

powerpc/powernv: Remove unused file

The patch removes unused file eeh-ioda.c and updates makefile
accordingly. Besides, the definition of "struct pnv_eeh_ops" and
the instances are all removed. Until now, the chip layer of EEH
implementation for PowerNV platform is removed completely.
