commit95566aa75cupstream. There is a possible double free issue in ppc4xx_trng_probe(): 85: dev->trng_base = of_iomap(trng, 0); 86: of_node_put(trng); ---> released here 87: if (!dev->trng_base) 88: goto err_out; ... 110: ierr_out: 111: of_node_put(trng); ---> double released here ... This issue was detected by using the Coccinelle software. We fix it by removing the unnecessary of_node_put().

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.
