Fixed this checkpatch CHECK:

CHECK: Macro argument 'rate' may be better as '(rate)' to avoid precedence issues
#133: FILE: drivers/i2c/busses/i2c-stm32f7.c:413:
+#define RATE_MIN(rate) (rate * 8 / 10)

and applied to for-next.

If you could drop the 'i2c-' prefix in $subject, that would save me one
