Dinghao Liu 088123ddb4 crypto: ccp - fix memleak in ccp_init_dm_workarea [ Upstream commit `a1c95dd5bc` ] When dma_map_single() fails, wa->address is supposed to be freed by the callers of ccp_init_dm_workarea() through ccp_dm_free(). However, many of the call spots don't expect to have to call ccp_dm_free() on failure of ccp_init_dm_workarea(), which may lead to a memleak. Let's free wa->address in ccp_init_dm_workarea() when dma_map_single() fails.

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.
