[ Upstream commit a91a0e774984aa57090c39dc3269a812417737ed ]
asihpi driver treats -1 as an own invalid PCM format, but this needs a proper cast with __force prefix since PCM format type is __bitwise. Define a constant with the proper type and use it allover.
This fixes sparse warnings like: sound/pci/asihpi/asihpi.c:315:9: warning: incorrect type in initializer (different base types)
