drivers/iommu/apple-dart-iommu.c:438:35-45: ERROR: function apple_dart_attach_stream called on line 519 inside lock on line 509 but uses GFP_KERNEL

 Find functions that refer to GFP_KERNEL but are called with locks held.

Semantic patch information:
 The proposed change of converting the GFP_KERNEL is not necessarily the
 correct one.  It may be desired to unlock the lock, or to not call the
 function under the lock in the first place.
