The probe function calls omap_gpio_show_rev(), which on most compilers is inlined, but on the old gcc-4.6 is not, causing a valid warning about the incorrect __init annotation: WARNING: vmlinux.o(.text+0x40f614): Section mismatch in reference from the function omap_gpio_probe() to the function .init.text:omap_gpio_show_rev() The function omap_gpio_probe() references the function __init omap_gpio_show_rev(). This is often because omap_gpio_probe lacks a __init annotation or the annotation of omap_gpio_show_rev is wrong. This removes the __init.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
