[PATCH] IPMI: return correct value from ipmi_write
This patch corrects the handling of write operations to the IPMI watchdog to work as intended by returning the number of characters actually processed. Without this patch, an "echo V >/dev/watchdog" enables the watchdog if IPMI is providing the watchdog function.
