Subject: [PATCH 2/2] can: mcp251xfd: mcp251xfd_chip_start(): fix error handling for mcp251xfd_chip_rx_int_enable()
Date: Sat, 6 Nov 2021 21:15:26 +0100 [thread overview]
Message-ID: <20211106201526.44292-2-mkl@pengutronix.de> (raw)
In-Reply-To: <20211106201526.44292-1-mkl@pengutronix.de>
This patch fixes the error handling for
mcp251xfd_chip_rx_int_enable(). Instead just returning the error,
properly shut down the chip in case of an error.
Fixes: 55e5b97f003e ("can: mcp25xxfd: add driver for Microchip MCP25xxFD SPI CAN")
