[ Upstream commit acb59a4bb8ed34e738a4c3463127bf3f6b5e11a9 ]
host_seq_bmp is allocated with vzalloc but is currently freed with
bitmap_free, which uses kfree internally. This mismach prevents the
resource from being released properly and may result in memory leaks
or other issues.
Fix this by freeing host_seq_bmp with vfree to match the vzalloc
allocation.

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.
