+Subject: hwrng: stm32 - fix unbalanced pm_runtime_enable
+
+From: Lionel Debieve <lionel.debieve@st.com>
+
+commit af0d4442dd6813de6e77309063beb064fa8e89ae upstream.
+
+No remove function implemented yet in the driver.
+Without remove function, the pm_runtime implementation
+complains when removing and probing again the driver.
