commit 1df83992d9 upstream.
If the total number of commands queried through TPM2_CAP_COMMANDS is
different from that queried through TPM2_CC_GET_CAPABILITY, it indicates
an unknown error. In this case, an appropriate error code -EFAULT should
be returned. However, we currently do not explicitly assign this error
code to 'rc'. As a result, 0 was incorrectly returned.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
