Rafael J. Wysocki f7c1b0e4ae thermal: core: Back off when polling thermal zones on errors ... Commit a8a2617744 ("thermal: core: Call monitor_thermal_zone() if zone temperature is invalid") introduced a polling mechanism by which the thermal core attampts to get a valid temperature value for thermal zones where the .get_temp() callback returns errors to start with (for example, due to initialization ordering woes). However, this polling is carried out periodically ad infinitum and every iteration of it causes a message to be printed to the kernel log which means a lot of log noise on systems where there are thermal zones that never get ready for some reason. It is also not really useful to continuously poll thermal zones that never respond. To address this, modify the thermal core to increase the delay between consecutive thermal zone temperature checks after every check that fails until it reaches a certain maximum value. At that point, the thermal zone in question will be disabled, but user space will be able to reenable it if it believes that the failure is transient. Also change the code to print messages regarding failed temperature checks to the kernel log only twice, once when the thermal zone's .get_temp() callback returns an error for the first time and once when disabling the given thermal zone. In addition, a dev_crit() message will be printed at that point if the given thermal zone contains a critical trip point to notify the system operator about the situation.
