Subject[PATCH] hwmon (occ): Fix response length in checksum retry
Date
Retrying for checksum failure doesn't work since the response length
gets zeroed out in the submit function. Fix this by resetting the
response length to its original value before the retry.

Fixes: c27b98ca0edb ("hwmon (occ): Retry for checksum failure")
