Lv Yunlong ef8e7bfea9 mtd: rawnand: gpmi: Fix a double free in gpmi_nand_init 
[ Upstream commit 076de75de1e53160e9b099f75872c1f9adf41a0b ]

If the callee gpmi_alloc_dma_buffer() failed to alloc memory for
this->raw_buffer, gpmi_free_dma_buffer() will be called to free
this->auxiliary_virt. But this->auxiliary_virt is still a non-NULL
and valid ptr.

Then gpmi_alloc_dma_buffer() returns err and gpmi_free_dma_buffer()
is called again to free this->auxiliary_virt in err_out. This causes
a double free.

As gpmi_free_dma_buffer() has already called in gpmi_alloc_dma_buffer's
error path, so it should return err directly instead of releasing the dma
buffer again.

README

README 

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.
