[PATCH V3 0/8] can: mcp251x: fix and optimize driver

[Marc Kleine-Budde <mkl-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>]

Moin,

this series of patches improves the mcp251x driver. It first fixes the
local_softirq_pending problem. Then the amount of SPI transfers is reduced
in order to optimise the driver. A further patch cleans up the chip model
selection.

This series has been tested with a mcp2515 on i.MX35.

Please review, test and consider to apply.

regards, Marc
