+Subject: [PATCH] pmdomain: core: add dummy release function to genpd device
|
|
|
+
|
|
|
+The genpd device, which is really only used as a handle to lookup
|
|
|
+OPP, but not even registered to the device core otherwise and thus
|
|
|
+lifetime linked to the genpd struct it is contained in, is missing
|
|
|
+a release function. After b8f7bbd1f4ec ("pmdomain: core: Add
|
|
|
+missing put_device()") the device will be cleaned up going through
|
|
|
+the driver core device_release() function, which will warn when no
|
|
|
+release callback is present for the device. Add a dummy release
|
|
|
+function to shut up the warning.
