Hi,
The releases 2.11.5 and 2.12.2 of LTTng-modules are bug fix releases, which

Using the fractional dividers requires some additional power bits to be
set.
The fractional power bits are not documented and the current heuristic
for setting them seems be insufficient for some cases. Just always set all
the fractional power bits when in fractional mod
let's use usb_find_common_endpoints() to discover endpoints, it does all
necessary checks for type and xfer direction
remove memset() in hfa384x_create(), because we now assign endpoints in
prism2sta_probe_usb() and because create_wlan() uses kzalloc() to
allocate hfa384x struct before calling hfa
