f32c80d342Add additional checks for program/config numbers to avoid loading from
invalid addresses.
If prm_no/cfg_no is negative, skip uploading program/config.
The tas2781-hda driver caused a NULL pointer dereference after loading
module, and before first runtime_suspend.
the state was:
tas_priv->cur_conf = -1;
tas_priv->tasdevice[i].cur_conf = 0;
program = &(tas_fmw->programs[-1]);

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.
