Therefore, ep is disabled before\ngserial_disconnect sets port to null to prevent this from happening.\n\nCall trace:\n gs_read_complete+0x58/0x240\n usb_gadget_giveback_request+0x40/0x160\n dwc3_remove_requests+0x170/0x484\n dwc3_ep0_out_start+0xb0/0x1d4\n __dwc3_gadget_start+0x25c/0x720\n kretprobe_trampoline.cfi_jt+0x0/0x8\n kretprobe_trampoline.cfi_jt+0x0/0x8\n udc_bind_to_driver+0x1d8/0x300\n usb_gadget_probe_driver+0xa8/0x1dc\n gadget_dev_desc_UDC_store+0x13c/0x188\n configfs_write_iter+0x160/0x1f4\n vfs_write+0x2d0/0x40c\n ksys_write+0x7c/0xf0\n __arm64_sys_write+0x20/0x30\n invoke_syscall+0x60/0x150\n el0_svc_common+0x8c/0xf8\n do_el0_svc+0x28/0xa0\n el0_svc+0x24/0x84\n\ud83d\udccf Published: 2025-01-19T11:52:36.460Z\n\ud83d\udccf Modified: 2025-01-19T11:52:36.460Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/3d730e8758c75b68a0152ee1ac48a270ea6725b4\n2. https://git.kernel.org/stable/c/0c50f00cc29948184af05bda31392fff5821f4f3\n3. https://git.kernel.org/stable/c/8e122d780a0f19aefd700dbd0b0e3ed3af0ae97f\n4. https://git.kernel.org/stable/c/13014969cbf07f18d62ceea40bd8ca8ec9d36cec", "creation_timestamp": "2025-01-19T11:58:33.000000Z"}
