[ Upstream commit 59f08896f058a92f03a0041b397a1a227c5e8529 ]
After commit 62974fc389b3 ("libnvdimm: Enable unit test infrastructure
compile checks"), clang warns:
In file included from
../drivers/nvdimm/../../tools/testing/nvdimm/test/iomap.c:15:
../drivers/nvdimm/../../tools/testing/nvdimm/test/nfit_test.h:206:15:
warning: redefinition of typedef 'acpi_handle' is a C11 feature
[-Wtypedef-redefinition]
typedef void *acpi_handle;
^
../include/acpi/actypes.h:424:15: note: previous definition is here
typedef void *acpi_handle; /* Actually a ptr to a NS Node */
^
1 warning generated.
The include chain:
iomap.c ->
linux/acpi.h ->
acpi/acpi.h ->
acpi/actypes.h
nfit_test.h
Avoid this by including linux/acpi.h in nfit_test.h, which allows us to
remove both the typedef and the forward declaration of acpi_object.
