Description

In the Linux kernel, the following vulnerability has been resolved: ice: Don't double unplug aux on peer initiated reset In the IDC callback that is accessed when the aux drivers request a reset, the function to unplug the aux devices is called. This function is also called in the ice_prepare_for_reset function. This double call is causing a "scheduling while atomic" BUG.
