commit9c8c5742b6upstream. platform_get_irq() calls dev_err() on an error. As the IRQ usage in the tpm_tis driver is optional, this is undesirable. Specifically this leads to this new false-positive error being logged: [ 5.135413] tpm_tis MSFT0101:00: IRQ index 0 not found This commit switches to platform_get_irq_optional(), which does not log an error, fixing this.

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.
