Guard functions in local_lock.h are defined using DEFINE_GUARD() and
DEFINE_LOCK_GUARD_1() macros having lock type defined as pointer in
the percpu address space. The functions, defined by these macros
return value in generic address space, causing:
cleanup.h:157:18: error: return from pointer to non-enclosed address space
and
cleanup.h:214:18: error: return from pointer to non-enclosed address space
when strict percpu checks are enabled.
Add explicit casts to remove address space of the returned pointer.
Found by GCC's named address space checks.
Fixes: e4ab322fba ("cleanup: Add conditional guard support")

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 reStructuredText 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.
