It is caused by the unnecessary use of WARN_ON\nin functionsfs_bind, which easily leads to the following scenarios.\n\n1.adb_write in adbd               2.

In this race scenario, the kernel panic\noccurs due to the WARN_ON from functionfs_bind when panic_on_warn is\nenabled. This commit fixes the kernel panic by removing the unnecessary\nWARN_ON.\n\nKernel panic - not syncing: kernel: panic_on_warn set ...\n[   14.542395] Call trace:\n[   14.542464]  ffs_func_bind+0x1c8/0x14a8\n[   14.542468]  usb_add_function+0xcc/0x1f0\n[   14.542473]  configfs_composite_bind+0x468/0x588\n[   14.542478]  gadget_bind_driver+0x108/0x27c\n[   14.542483]  really_probe+0x190/0x374\n[   14.542488]  __driver_probe_device+0xa0/0x12c\n[   14.542492]  driver_probe_device+0x3c/0x220\n[   14.542498]  __driver_attach+0x11c/0x1fc\n[   14.542502]  bus_for_each_dev+0x104/0x160\n[   14.542506]  driver_attach+0x24/0x34\n[   14.542510]  bus_add_driver+0x154/0x270\n[   14.542514]  driver_register+0x68/0x104\n[   14.542518]  usb_gadget_register_driver_owner+0x48/0xf4\n[   14.542523]  gadget_dev_desc_UDC_store+0xf8/0x144\n[   14.542526]  configfs_write_iter+0xf0/0x138"
