   4 Subject: [PATCH] wireless: Use linux/stddef.h instead of stddef.h
   5
   6 When compiling inside the kernel include linux/stddef.h instead of
   7 stddef.h. When I compile this header file in backports for power PC I
   8 run into a conflict with ptrdiff_t. I was unable to reproduce this in
   9 mainline kernel. I still would like to fix this problem in the kernel.
