can: mcp251xfd: mcp251xfd_register_get_dev_id(): fix return of error value

2022-04-08T12:06:49Z

commit fa7b514d2b2894e052b8e94c7a29feb98e90093f upstream. Clang static analysis reports this issue: | mcp251xfd-core.c:1813:7: warning: The left operand | of '&' is a garbage value | FIELD_GET(MCP251XFD_REG_DEVID_ID_MASK, dev_id), | ^ ~~~~~~ dev_id is set in a successful call to mcp251xfd_register_get_dev_id(). Though the status of calls made by mcp251xfd_register_get_dev_id() are checked and handled, their status' are not returned. So return err.

can: mcp251xfd: mcp251xfd_chip_start(): fix error handling for mcp251xfd_chip_rx_int_enable()

2021-11-06T20:25:25Z

This patch fixes the error handling for mcp251xfd_chip_rx_int_enable(). Instead just returning the error, properly shut down the chip.

can: mcp251xfd: mcp251xfd_irq(): add missing can_rx_offload_threaded_irq_finish() in case of bus off

2021-11-06T20:15:32Z

The function can_rx_offload_threaded_irq_finish() is needed to trigger the NAPI thread to deliver read CAN frames to the networking stack. This patch adds the missing call to can_rx_offload_threaded_irq_finish() in case of a bus off, before leaving the interrupt handler to avoid packet starvation.

can: mcp251xfd: mark some instances of struct mcp251xfd_priv as const

2021-08-19T13:07:03Z

With the patch 07ff4aed015c ("time/timecounter: Mark 1st argument of timecounter_cyc2time() as const") some instances of the struct mcp251xfd_priv can be marked as const. This patch marks these as const. Link: https://lore.kernel.org/r/20210813091027.159379-1-mkl@pengutronix.de Cc: Manivannan Sadhasivam Cc: Thomas Kopp Signed-off-by: Marc Kleine-Budde

The hi3110_cmd() is supposed to return zero on success and negative error codes on failure, but it was accidentally declared as a u8 when it needs to be an int type.
