The __printf() macro is used in many tools in the linux kernel to validate the format specifiers in functions that use printf. The kvm selftest uses it without putting it in a macro definition while it also imports the kselftests.h header where the macro attribute is defined.
Use __printf() from kselftests.h instead of the full attribute.
Signed-off-by: Maciej Wieczor-Retman maciej.wieczor-retman@intel.com --- Changelog v6: - Make the motivation behind the patch more explicit in the patch message.
Changelog v2: - Reword patch message. - Use __printf() on test_assert().
