Linux kernel source tree
07d8004d6f
Add a new `bufsiz` parameter to the `.send` callback in `tpm_class_ops`. This parameter will allow drivers to differentiate between the actual command length to send and the total buffer size. Currently `bufsiz` is not used, but it will be used to implement devices with synchronous send() to send the command and receive the response on the same buffer. Also rename the previous parameter `len` to `cmd_len` in the declaration to make it clear that it contains the length in bytes of the command stored in the buffer. The semantics don't change and it can be used as before by drivers. This is an optimization since the drivers could get it from the header, but let's avoid duplicating code. While we are here, resolve a checkpatch warning: WARNING: Unnecessary space before function pointer arguments #66: FILE: include/linux/tpm.h:90: + int (*send) (struct tpm_chip *chip, u8 *buf, size_t bufsiz, Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Suggested-by: Jarkko Sakkinen <jarkko@kernel.org> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> |

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 reStructuredText 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.
