The correct patch is [1]. [1]: https://lore.kernel.org/lkml/bb43ff8ad9e0b9884722d85e51c8fdb3ef4154d1.1591136989.git.gurus@codeaurora.org/ Thank you. Guru Das.

Since the PWM framework is switching struct pwm_state.period's datatype to u64, prepare for this transition by using DIV_ROUND_UP_ULL to handle a 64-bit dividend. Signed-off-by: Guru Das Srinagesh <gurus@codeaurora.org> --- drivers/pwm/pwm-imx27.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
