hwmon: (occ) Store error condition for rate-limited polls
The OCC driver limits the rate of sending poll commands to the OCC. If a user reads a hwmon entry after a poll response resulted in an error and is rate-limited, the error is invisible to the user. Fix this by storing the last error and returning that in the rate-limited case. Signed-off-by: Eddie James <eajames@linux.ibm.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
