R. Silva <gustavo@embeddedor.com> Patchwork seems to have missed my earlier reply with my Reviewed-by:. (https://patchwork.ozlabs.org/patch/1220206/ only has Clément's reply that still contains my quoted text, but obviously this wasn't picked up by patchwork.) So resending it in the hope this was a one-time miss: Reviewed-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Best regards Uwe

Fix inconsistent IS_ERR and PTR_ERR in sun4i_pwm_probe(). The proper pointers to be passed as arguments are pwm->clk and pwm->bus_clk. This bug was detected with the help of Coccinelle.
