2021-10-22	fsi: sbefifo: Use interruptible mutex locking	Eddie James	1	-3/+9
	Some SBE operations have extremely large responses and can require several minutes to process the response. During this time, the device lock must be held. If another process attempts an operation, it will wait for the mutex for longer than the kernel hung task watchdog allows. Therefore, use the interruptible function to lock the mutex.

2021-10-22	fsi: sbefifo: Add sysfs file indicating a timeout error	Eddie James	1	-0/+16
	The SBEFIFO timeout error requires special handling in userspace to do recovery operations. Add a sysfs file to indicate a timeout error, and notify pollers when a timeout occurs. This will be used by the openpower-occ-control application.
