When compiling inside the kernel include linux/stddef.h instead of stddef.h. When I compile this header file in backports for power PC I run into a conflict with ptrdiff_t. I was unable to reproduce this in mainline kernel. I still would like to fix this problem in the kernel. Fixes: 6989310f5d43 ("wireless: Use offsetof instead of custom macro.")
