savagefb_probe() calls savage_init_fb_info() that can successfully allocate memory for info->pixmap.addr but then fail when fb_alloc_cmap() fails. savagefb_probe() goes to label failed_init and does not free allocated memory. It is not valid to go to label failed_mmio since savage_init_fb_info() can fail during memory allocation as well. So, the patch free allocated memory on the error handling path in savage_init_fb_info() itself. Found by Linux Driver Verification project (linuxtesting.org).

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.
