Device number (the character device index) is not a stable identifier for a TPM chip. That is the reason why every call site passes TPM_ANY_NUM to tpm_chip_find_get(). This commit changes the API in a way that instead a struct tpm_chip instance is given and NULL means the default chip. In addition, this commit refines the documentation to be up to date with the implementation.

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.
