In ull_disable, it is imperative that the callback is set up before a second reference counter check, otherwise it may happen that an LLL done event has already passed when the disable callback and semaphore is assigned. This causes the HCI thread to wait until timeout and assert after ull_ticker_stop_with_mark. For certain compilers, due to compiler optimizations, it can be seen from the assembler code that the callback is assigned after the second reference counter check. By adding memory barriers, the code correctly reorders code to the expected sequence. Signed-off-by: Morten Priess <[email protected]>

A Host shall consider any error code that it does not explicitly understand equivalent to the error code Unspecified Error (0x1F). Signed-off-by: Vinayak Kariappa Chettimada <[email protected]>

Refactor reused function in BT_CTLR_LE_ENC feature.|
In ull_disable, it is imperative that the callback is set up before a
second reference counter check, otherwise it may happen that an LLL done
event has already passed when the disable callback and semaphore is
assigned.
This causes the HCI thread to wait until timeout and assert after
ull_ticker_stop_with_mark.
For certain compilers, due to compiler optimizations, it can be seen
from the assembler code that the callback is assigned after the second
reference counter check.
By adding memory barriers, the code correctly reorders code to the
expected sequence.
Fixes #75981.
