If anyone has any objections, please let me know. ------------------ From: Andy Shevchenko [ Upstream commit 5e57418a2031cd5e1863efdf3d7447a16a368172 ] It appears that compiler_types.h already have an implementation of the __unconst_integer_typeof() called __unqual_scalar_typeof(). Use it instead of the copy.
