3.16.62-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Iwai <[email protected]> commit a49a71f6e25da2acc637fcd31e73debd96ca18f8 upstream. The sanity checks in ALSA sequencer and OSS sequencer emulation codes return falsely -ENXIO from poll callback. They should be EPOLLERR instead. This was caught thanks to the recent change to the return value.
