X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=53876e387d962f7f37747150f33f2aa920a7b20c;p=linux-beck.git powerpc: Lack of ibm,io-events not that important! The ibm,io-events code is a bit verbose with its error messages. Reverse the reporting so we only print when we successfully enable I/O event interrupts.
