[PATCH v1 0/2] MPAM Fixes for UAF and NPE on unbind

[Ben Horgan]

The MPAM driver expects to manage all the MSC in a system. At boot it
delays its initialization until it has probed all of them but once
running it is unprepared to have the MSC taken away and that can trigger
UAF and NPE. Workaround this by ensuring it never relinquishes the MSC.

  arm_mpam: Fix a NULL pointer dereference on unbinding after an error
    interrupt
  arm_mpam: Disable driver unbind to avoid UAF
