3Fix type conversion for x32. For x32 the off_t is 64bit and pointers are 32bit.
4so the conversion of pointer to off_t was resulting into this error:

6| XF86DGA2.c:931:24: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
7| cc1: some warnings being treated as errors

11Fixed it by typecasting pointer into unsigned long 1st and then again typecasting
12unsigned long to off_t.
