STM32L4 sleep broke between #137 and #138

I believe I have seen this problem here some time ago in the forum, but cannot find it here or on github anymore.

Doing a simple sleep in the main function, the sleep returns immediately without waiting for a wakeup interrupt events. Up to #137 (mbed classic tested) it works as expected. Starting with #138 the problem occurs.

Does somebody knows if this has already been reported.

Hi Helmut

Looking in our log file here https://developer.mbed.org/teams/ST/wiki/SDK-changes-log#v138-17w11 I can see some changes for the L4 concerning a fix for DeepSleep. Need to dig deeper in GitHub history to find more details...
