Message-Id: <20231005195812.549776-28-mkl@pengutronix.de> Date: Thu, 5 Oct 2023 21:58:02 +0200 From: Marc Kleine-Budde <mkl@...gutronix.de> To: netdev@...r.kernel.org Cc: davem@...emloft.net, kuba@...nel.org, linux-can@...r.kernel.org, kernel@...gutronix.de, Marc Kleine-Budde <mkl@...gutronix.de> Subject: [PATCH net-next 27/37] can: at91_can: at91_poll_err(): fold in at91_poll_err_frame() This is a preparation patch for the cleanup of at91_poll_err(). Fold at91_poll_err_frame() into at91_poll_err() so that it can be easier modified.
