[codemod][bugfix] Fix addressing bug in caffe2/caffe2/video/video_input_op.h (#121856)
Summary:
# Diff Specific
The signature of `copyFrom` is
```
void Tensor::CopyFrom(const Tensor& src, bool async) {
```
so the `&context` always evaluated to true.
I could dig around to see if anyone cares about what the flag should actually be, but this is old code in caffe2, so I've just used `true` and we'll keep using whatever behaviour we've been using since 2019 or so when this was written.
# General
A bug in this code was identified by `-Waddress`, which we are working to enable globally.
This diff fixes the bug. There are a few types of fixes it might employ:
The bug could be `const_char_array == "hello"` which compares two addresses and therefore is almost always false. This is fixed with `const_char_array == std::string_view("hello")` because `string_view` has an `==` operator that makes an appropriate comparison.
The bug could be `if(name_of_func)` which always returns true because the function always has an address. Likely you meant to call the function here!
