+Upstream-Status: pending
+
+Fix type conversion for x32. For x32 the off_t is 64bit and pointers are 32bit.
+so the conversion of pointer to off_t was resulting into this error:
+
+| XF86DGA2.c:931:24: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
+| cc1: some warnings being treated as errors
+| 
+| make[2]: *** [XF86DGA2.lo] Error 1
+
+Fixed it by typecasting pointer into unsigned long 1st and then again typecasting 
+unsigned long to off_t.
