Chuhong Yuan a29e1012c1 RDMA/uverbs: Add a check for uverbs_attr_get to uverbs_copy_to_struct_or_zero
All current callers for uverbs_copy_to_struct_or_zero() already check that
the attribute exists, but it make sense to verify the result like the
other functions do.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
