Hey @kulinseth.
You've committed this PR, but it does not have both a 'release notes: ...' and 'topics: ...' label. Please add one of each to the PR. The 'release notes: ...' label should represent the part of PyTorch that this PR changes (fx, autograd, distributed, etc) and the 'topics: ...' label should represent the kind of PR it is (not user facing, new feature, bug fix, perf improvement, etc). The list of valid labels can be found here for the 'release notes: ...' and here for the 'topics: ...'.
For changes that are 'topic: not user facing' there is no need for a release notes label.

* [MPS] Fix binary ops between int32 tensor with int64 scalar (#80220)

For some reason, tensor *op* scalar does not follow the normal binary promotion rules
So cast output tensor to expected type if needed
It seems that one should have casted input tensors to expected output tensor type, but it does not really work for boolean binary ops, so...
Add output tensor type/shape to cached graph key
Extend `TestMPS. test_add_scalars` to test for this regression
