__snd_vortex_probe() uses pci_read_config_word() that returns PCIBIOS_* codes (positive values on error). However, the function checks 'err < 0' which can never be true for PCIBIOS_* codes, causing errors to be silently ignored. Check for non-zero return value and convert PCIBIOS_* codes using pcibios_err_to_errno() into normal errno before returning them.

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.
