Another small batch of patches to be seen as preparation for adding support of the newly available esd CAN-USB/3 to esd_usb.c. Due to some unresolved questions adding support for CAN_CTRLMODE_BERR_REPORTING has been postponed to one of the future patches. *Resend of the whole series as v3 for easier handling.* --- * Changelog * v2 -> v3: * More specific subjects * Try to use imperative instead of past tense v1 -> v2: * [Patch v2 1/3]: No changes. * [Patch v2 2/3]: Make use of can_change_state() and relocate testing alloc_can_err_skb() for NULL to the end of esd_usb_rx_event(), to have things like can_bus_off(), can_change_state() working even in out of memory conditions. * [Patch v2 3/3]: No changes. I will 'declare esd_usb_msg as an union instead of a struct' in a separate follow-up patch. v1: Link: https://lore.kernel.org/all/20221219212013.1294820-1-frank.jungclaus@xxxxxx/ Link: https://lore.kernel.org/all/20221219212717.1298282-1-frank.jungclaus@xxxxxx/ Frank Jungclaus (3): can: esd_usb: Move mislocated storage of SJA1000_ECC_SEG bits in case of a bus error can: esd_usb: Make use of can_change_state() and relocate checking skb for NULL can: esd_usb: Improve readability on decoding ESD_EV_CAN_ERROR_EXT messages drivers/net/can/usb/esd_usb.c | 70 ++++++++++++++++++++--------------- 1 file changed, 40 insertions(+), 30 deletions(-) base-commit: fa1d915a624f72b153a9ff9700232056758a2b6c -- 2.25.1
