This patchset fixes a few issues with emission of HCI Remove CIG, Set CIG Parameters, Create CIS when multiple ISO sockets in the same CIG are closed and reconnected rapidly. These were found when trying to make Samsung Galaxy Buds2 Pro stream disabling and re-enabling work, and with a few additional emulator test improvements. In these cases, the user is closing and reconnecting ISO sockets rapidly. With this and the associated BlueZ patchset, disabling and re-enabling streams on this device works correctly and the problem in https://github.com/bluez/bluez/issues/516 is solved; this kernel patchset contains nothing device specific though. The last Create CIS patch probably could be done in different ways, but seemed simplest to have hci_le_create_cis_sync be idempotent.
