Subject: [PATCH 03/19 v6.1.y] minmax: deduplicate __unconst_integer_typeof()
From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
[ 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.
