[Piglit] [PATCH 3/3] Fix a bug in get-program-build-info.c

[junyan.he at linux.intel.com]

From: Junyan He <junyan.he at linux.intel.com>

The case:
Trigger CL_INVALID_VALUE if size in bytes specified by param_value
is less than size of return type and param_value is not a NULL value.
This case will sometime pass the param_value NULL to the function call
and cause the check failed.
