Upon usb composition switch there is possibility of ep0 file release happening after gadget driver bind. In case of composition switch from adb to a non-adb composition gadget will never gets bound again resulting into failure of usb device enumeration. Fix this issue by checking FFS_FL_BOUND flag and avoid extra gadget driver unbind if it is already done as part of composition switch. This fixes adb reconnection error reported on Android running v4.4 and above kernel versions. Verified on Hikey running vanilla v4.15-rc7 + few out of tree Mali patches.

The logic of the original commit 4d99b2581eff ("staging: lustre: avoid intensive reconnecting for ko2iblnd") was assumed conditional free of struct kib_conn if the second argument free_conn in function kiblnd_destroy_conn(struct kib_conn *conn, bool free_conn) is true. But this hunk of code was dropped from original commit. As result the logic works wrong and current code use struct kib_conn after free. > drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c > 3317 kiblnd_destroy_conn(conn, !peer); > ^^^^ Freed always (but should be conditionally) > 3318 > 3319 spin_lock_irqsave(lock, flags); > 3320 if (!peer) > 3321 continue; > 3322 > 3323 conn->ibc_peer = peer; > ^^^^^^^^^^^^^^ Use after free > 3324 if (peer->ibp_reconnected < KIB_RECONN_HIGH_RACE) > 3325 list_add_tail(&conn->ibc_list, > ^^^^^^^^^^^^^^ Use after free > 3326 &kiblnd_data.kib_reconn_list); > 3327 else > 3328 list_add_tail(&conn->ibc_list, > ^^^^^^^^^^^^^^ Use after free > 3329 &kiblnd_data.kib_reconn_wait); To avoid confusion this fix moved the freeing a struct kib_conn outside of the function kiblnd_destroy_conn() and free as it was intended in original commit.
