This looks like what was intended.

Dropped use of intAttr and used intVal instead.

Why though? That will result in an unnecessary dyn_cast to Value:

https://github.com/llvm/llvm-project/blob/ba72cfe73464b9f1e06f2cd2bed93b07483c0be1/mlir/lib/Dialect/Utils/StaticValueUtils.cpp#L69

I assume the original intention was avoiding that, given the assert message.

mlir/lib/Dialect/Linalg/IR/LinalgOps.cpp

 // Methods related to PadTensor tiling.
 //===----------------------------------------------------------------------===//
 
 /// Given an OpFoldResult, return a Value. If the OpFoldResult is an Attribute,
 /// it must be of type Integer.
 static Value getAsValue(OpBuilder &builder, Location loc, OpFoldResult ofr) {
   if (auto val = ofr.dyn_cast<Value>())
     return val;
   auto intVal = getConstantIntValue(ofr);
-  auto intAttr = ofr.dyn_cast<Attribute>().dyn_cast_or_null<IntegerAttr>();
   assert(intVal && "expected Value or IntegerAttr");
-  return builder.create<ConstantIndexOp>(loc, intAttr.getInt());
+  return builder.create<ConstantIndexOp>(loc, *intVal);
 }
 
 SmallVector<Value> PadTensorOp::getDestinationOperands(OpBuilder &b) {
   ReifiedRankedShapedTypeDims reifiedShapes;
   (void)reifyResultShapes(b, reifiedShapes);
   Value initTensor = b.create<InitTensorOp>(getLoc(), reifiedShapes[0],
                                             getResultType().getElementType());
   return {initTensor};
