rk_gmac_setup() delves into the PHY's DT node to retrieve its reset control using of_reset_control_get(). However, it never releases it when the driver is removed. Add reset_control_put() to rk_gmac_exit() to clean this up. Signed-off-by: Russell King (Oracle) <redacted> --- drivers/net/ethernet/stmicro/stmmac/dwmac-rk.c | 2 ++ 1 file changed, 2 insertions(+)
