This patch fixes several checkpatch warnings in the c_can_platform driver glue code. Signed-off-by: Marc Kleine-Budde

can: c_can: C_CAN: add bus recovery events

2019-11-04T20:47:21Z

While the state is updated when the error counters increase and decrease, there is no event when the bus recovers and the error counters decrease again. So add that event as well. Change the state going downward to be ERROR_PASSIVE -> ERROR_WARNING -> ERROR_ACTIVE instead of directly to ERROR_ACTIVE again.

can: c_can: D_CAN: c_can_chip_config(): perform a sofware reset on open

2019-11-04T20:47:21Z

When the CAN interface is closed it the hardwre is put in power down mode, but does not reset the error counters / state. Reset the D_CAN on open, so the reported state and the actual state match. According to [1], the C_CAN module doesn't have the software reset.

can: c_can: c_can_poll(): only read status register after status IRQ

2019-11-04T20:47:21Z

When the status register is read without the status IRQ pending, the chip may not raise the interrupt line for an upcoming status interrupt and the driver may miss a status interrupt. It is critical that the BUSOFF status interrupt is forwarded to the higher layers, since no more interrupts will follow without intervention. Thanks to Wolfgang and Joe for bringing up the first idea.

Make c_can_pci_data structures const as they are only used during a copy operation. Signed-off-by: Bhumika Goyal Signed-off-by: Marc Kleine-Budde

can: c_can: don't indicate triple sampling support for D_CAN

2017-11-10T08:15:28Z

The D_CAN controller doesn't provide a triple sampling mode, so don't set the CAN_CTRLMODE_3_SAMPLES flag in ctrlmode_supported. Currently enabling triple sampling is a no-op. Signed-off-by: Richard Schütz Cc: linux-stable # >= v3.6 Signed-off-by: Marc Kleine-Budde

can: constify platform_device_id

2017-08-14T03:12:23Z

platform_device_id are not supposed to change at runtime. All functions working with platform_device_id provided by work with const platform_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: David S. Miller

drivers: net: generalize napi_complete_done()

2017-01-30T20:10:42Z

napi_complete_done() allows to opt-in for gro_flush_timeout, added back in linux-3.19, commit 3b47d30396ba ("net: gro: add a per device gro flush timer") This allows for more efficient GRO aggregation without sacrifying latencies. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

can: c_can_pci: fix null-pointer-deref in c_can_start() - set device pointer

2017-01-18T11:58:26Z

The priv->device pointer for c_can_pci is never set, but it is used without a NULL check in c_can_start(). Setting it in c_can_pci_probe() like c_can_plat_probe() prevents c_can_pci.ko from crashing, with and without CONFIG_PM. This might also cause the pm_runtime_*() functions in c_can.c to actually be executed for c_can_pci devices - they are the only other place where priv->device is used, but they all contain a null check.
