include/linux/local_lock_internal.h: Make this header file again compatible with sparse
There are two versions of the __this_cpu_local_lock() definitions in
include/linux/local_lock_internal.h: one version that relies on the
Clang overloading functionality and another version that does not.
Select the latter version when using sparse. This patch fixes the
following errors reported by sparse:
include/linux/local_lock_internal.h:331:40: sparse: sparse: multiple definitions for function '__this_cpu_local_lock'
include/linux/local_lock_internal.h:325:37: sparse: the previous one is here
Closes: https://lore.kernel.org/oe-kbuild-all/202603062334.wgI5htP0-lkp@intel.com/
Fixes: d3febf16dee2 ("locking/local_lock: Support Clang's context analysis")
