+Subject: [PATCH] wireless: Use linux/stddef.h instead of stddef.h
+
+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.")
