This rewrites the MKSTR macro appending an empty string to its arguments
to resolve build failures similar to:
drivers/net/mlx4/mlx4.c:461:14: fatal error: format string is not a
string literal [-Wformat-nonliteral]
MKSTR(path, "%s/device/uevent", device->ibdev_path);
drivers/net/mlx4/mlx4_utils.h:82:30: note: expanded from macro 'MKSTR'
char name[snprintf(NULL, 0, __VA_ARGS__) + 1]; \
drivers/net/mlx5/mlx5_stats.c:144:15: fatal error: format string is not a
string literal [-Wformat-nonliteral]
MKSTR(path, "%s/ports/%d/hw_counters/%s",
drivers/net/mlx5/mlx5_utils.h:149:30: note: expanded from macro 'MKSTR'
char name[snprintf(NULL, 0, __VA_ARGS__) + 1]; \
The errors reproduce with clang version 9.0.0, and the release notes
don't mention what could have caused them.
