This leads the following spinlock bad magic complaint from the kernel, eg. when trying to send CAN frames with cansend from can-utils: | BUG: spinlock bad magic on CPU#0, cansend/95 | lock: 0xff60000002ec1010, .magic: 00000000, .owner: /-1, .owner_cpu: 0 | CPU: 0 UID: 0 PID: 95 Comm: cansend Not tainted 6.15.0-rc3-00032-ga79be02bba5c #5 NONE | Hardware name: MachineWare SIM-V (DT) | Call Trace: | [] dump_backtrace+0x1c/0x24 | [] show_stack+0x28/0x34 | [] dump_stack_lvl+0x4a/0x68 | [] dump_stack+0x14/0x1c | [] spin_dump+0x62/0x6e | [] do_raw_spin_lock+0xd0/0x142 | [] _raw_spin_lock_irqsave+0x20/0x2c | [] m_can_start_xmit+0x90/0x34a | [] dev_hard_start_xmit+0xa6/0xee | [] sch_direct_xmit+0x114/0x292 | [] __dev_queue_xmit+0x3b0/0xaa8 | [] can_send+0xc6/0x242 | [] raw_sendmsg+0x1a8/0x36c | [] sock_write_iter+0x9a/0xee | [] vfs_write+0x184/0x3a6 | [] ksys_write+0xa0/0xc0 | [] __riscv_sys_write+0x14/0x1c | [] do_trap_ecall_u+0x168/0x212 | [] handle_exception+0x146/0x152 Initializing the spin lock in m_can_class_allocate_dev solves that problem.
