can: pcan_usb: add support of rxerr/txerr counters

2020-09-21T08:13:18Z

This patch adds the support of the rx/tx errors CAN counters to the driver of the PCAN-USB PC-CAN interface from PEAK-System GmbH. The PCAN-USB is capable of giving back the values of the rx/tx errors counters, to provide more details and statistics to the linux-can layer. Getting these values allows the driver to better tune CAN_ERR_CRTL_TX_xxx and CAN_ERR_CRTL_RX_xxx bits in case of the interface enters any CAN_STATE_ERROR_xxx state.

can: mcba_usb: remove redundant initialization of variable err

2020-09-21T08:13:17Z

The variable err is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

can: kvaser_usb: fix interface sanity check

2020-01-02T14:34:27Z

Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.
