i2c: testunit: improve error handling for GPIO
Bail out in probe if getting the optional GPIO returns an error. Bail out in the test early if the optional GPIO is not present, otherwise the timeout errno is misleading. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>
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.
