Not all platforms use those. Let's use platform_get_irq_byname_optional() instead platform_get_irq_byname() so that we avoid a useless warning: [ 1.359455] pxa-gpio d4019000.gpio: IRQ gpio0 not found [ 1.359583] pxa-gpio d4019000.gpio: IRQ gpio1 not found Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.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 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.
