[PATCH 0/4] occ: fsi and hwmon: Fixes for polling un-initialized OCC

From: Eddie James
Date: Tue Feb 09 2021 - 12:14:49 EST


In the event that the OCC is not initialized when the driver sends a poll
command, the driver may receive an invalid response. This isn't an error
condition unless there is no valid response before the timeout expires. So
change the starting sequence number and check for the un-initialized OCC
state before returning the response in order to detect this condition and
continue waiting if necessary.

Eddie James (4):
fsi: occ: Don't accept response from un-initialized OCC
fsi: occ: Log error for checksum failure
hwmon: (occ) Start sequence number at one
hwmon: (occ) Print response status in first poll error message
