[PATCH 3.14 12/52] scsi: correct return values for .eh_abort_handler implementations

From: Greg Kroah-Hartman
Date: Tue Jan 06 2015 - 21:47:04 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Hannes Reinecke <hare@xxxxxxx>

commit b6c92b7e0af575e2b8b05bdf33633cf9e1661cbf upstream.

The .eh_abort_handler needs to return SUCCESS, FAILED, or
FAST_IO_FAIL. So fixup all callers to adhere to this requirement.
