From: Ivan Lipski <ivlipski@xxxxxxx> [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.
