From: Nitin A Kamble <nitin.a.kam...@intel.com> 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.
