commita05a140499upstream. The change corrects the error path in gpiochip_add_data_with_key() by avoiding to call ida_simple_remove(), if ida_simple_get() returns an error. Note that ida_simple_remove()/ida_free() throws a BUG(), if id argument is negative, it allows to easily check the correctness of the fix by fuzzing the return value from ida_simple_get().

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.
