commit 1b9ae0c92925ac40489be526d67d0010d0724ce0 upstream.
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.")
