-Subject: [PATCH] firmware: raspberrypi: Add backward compatible
- get_throttled
-
-Avoid a hard userspace ABI change by adding a compatible get_throttled
-sysfs entry. Its value is now feed by the GET_THROTTLED requests of the
-new hwmon driver. The first access to get_throttled will generate
-a warning.
