Subject: [PATCH] rapidio: fix RapidIO sysfs hierarchy
This set of RapidIO patches extends support for standard error recovery
mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and
CPS-1616. Implementation of the standard error-stopped state recovery
mechanism (as defined by the RapidIO specification) is required for the
new switches.
Version 2 of this set of patches addresses received comments and fixes an
error notification setup issue found in the idt_gen2.c after the first
version was released.
This patch:
Make RapidIO devices appear in /sys/devices/rapidio directory instead of
top of /sys/devices directory.
