Bartosz Golaszewski 1c753d001a firmware: qcom: tzmem: fix virtual-to-physical address conversion
We currently only correctly convert the virtual address passed by the
caller to qcom_tzmem_to_phys() if it corresponds to the base address of
the chunk. If the user wants to convert some pointer at an offset
relative to that base address, we'll return 0. Let's change the
implementation of qcom_tzmem_to_phys(): iterate over the chunks and try
to call gen_pool_virt_to_phys() just-in-time instead of trying to call
it only once when creating the chunk.

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.
