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]
