[ Upstream commit4b553f3ca4] In function ath10k_sdio_mbox_rx_alloc() [sdio.c], ath10k_sdio_mbox_alloc_rx_pkt() is called without handling the error cases. This will make the driver think the allocation for skb is successful and try to access the skb. If we enable failslab, system will easily crash with NULL pointer dereferencing.

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.
