From: Jingoo Han <jg1.han@...sung.com>
To: "'David S. Miller'" <davem@...emloft.net>
Cc: netdev@...r.kernel.org, 'Jingoo Han' <jg1.han@...sung.com>
Subject: [PATCH 2/7] net: can: mcp251x: use spi_get_drvdata() and
spi_set_drvdata()
Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.
