| 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. |
