7.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Nikhil Gurudasani commit 9607c245ca6674955e5e43e3606db410ae9e0b90 upstream. When a device is in standby, the driver starts a one-shot conversion and polls the BUSY flag before reading temperature, alarm, or fault data. The poll result is currently ignored. Therefore, a timeout or a status-register read failure can be hidden by a later successful read, causing stale data to be returned as valid. Return the polling error before reading the requested attribute.
