[PATCH] powernv/opal: Handle OPAL_WRONG_STATE error from OPAL fails
From: Vipin K Parashar <hidden>

Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
Added check for OPAL_WRONG_STATE error code returned from OPAL. Currently Linux flashes "unexpected error" over console for this error. This will avoid throwing such message and return I/O error for such OPAL failures.
