suggestion:

	const uint8_t *const buf  => const uint8_t *buf
	const uint32_t size       => uint32_t size
	const uint32_t offset     => uint32_t offset

What was done:

-static int stfsm_write_fifo(struct stfsm *fsm,
-                           const uint32_t *buf, const uint32_t size)
+static int stfsm_write_fifo(struct stfsm *fsm, uint32_t *buf, uint32_t size)

Note the removal of the const from uint32_t *buf

Why?
