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.
