X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ffefb8eaa367e8a5c14f779233d9da1fbc23d164;p=linux-beck.git ore: Fix crash in case of an IO error. The users of ore_check_io() expect the reported device (In case of error) to be indexed relative to the passed-in ore_components table, and not the logical dev index. This causes a crash inside objlayoutdriver in case of an IO error.
