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.
