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
