In the unlikely case when alloc_irq_table() is not able to return a remap table then "ret" will be assigned with an error code. Later, the code checks `index' and if it is negative (which it is because it is initialized with `-1') and then then function properly aborts but returns `-1' instead `-ENOMEM' what was intended. In order to correct this, I assign -ENOMEM to index. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Joerg Roedel <jroedel@suse.de>
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.
