From: Ivan Lipski <ivlip...@amd.com>
[WHY]
Coverity analysis flagged this ternary operation as
DEADCODE.
Since 'total_y_free_entry' is initialized as 0x200 and
'total_c_free_entry' is initialized as 0x140, and they
never change values before the ternary operator, so
'total_y_free_entry' is always greater 'total_c_free_entry',
'so small_free_entry' is always set to 'total_c_free_entry'.
[HOW]
Replace the ternary operator with the variable declaration.
