Marc Kleine-Budde says: ==================== pull-request: can 2026-03-02 The first 2 patches are by Oliver Hartkopp. The first fixes the locking for CAN Broadcast Manager op runtime updates, the second fixes the packet statisctics for the CAN dummy driver. Alban Bedel's patch fixes a potential problem in the error path of the mcp251x's ndo_open callback. A patch by Ziyi Guo add USB endpoint type validation to the esd_usb driver. The next 6 patches are by Greg Kroah-Hartman and fix URB data parsing for the ems_usb and ucan driver, fix URB anchoring in the etas_es58x, and in the f81604 driver fix URB data parsing, add URB error handling and fix URB anchoring. A patch by me targets the gs_usb driver and fixes interoperability with the CANable-2.5 firmware by always configuring the bit rate before starting the device. The last patch is by Frank Li and fixes a CHECK_DTBS warning for the nxp,sja1000 dt-binding. * tag 'linux-can-fixes-for-7.0-20260302' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: dt-bindings: net: can: nxp,sja1000: add reference to mc-peripheral-props.yaml can: gs_usb: gs_can_open(): always configure bitrates before starting device can: usb: f81604: correctly anchor the urb in the read bulk callback can: usb: f81604: handle bulk write errors properly can: usb: f81604: handle short interrupt urb messages properly can: usb: etas_es58x: correctly anchor the urb in the read bulk callback can: ucan: Fix infinite loop from zero-length messages can: ems_usb: ems_usb_read_bulk_callback(): check the proper length of a message can: esd_usb: add endpoint type validation can: mcp251x: fix deadlock in error path of mcp251x_open can: dummy_can: dummy_can_init(): fix packet statistics can: bcm: fix locking for bcm_op runtime updates ==================== Link: https://patch.msgid.link/20260302152755.1700177-1-mkl@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>
