Commit ee65ad0e2a9e ("backlight: pwm_bl: Avoid backlight flicker when probed from DT") tries to dereference the device of_node pointer unconditionally, causing a NULL pointer dereference on non-dt platforms. Fix it by replacing the phandle variable with a node variable and by checking that for NULL before dereferencing it.
