linux-libc-headers: Include linux/stddef.h in linux/swab.h
This helps compiling bpf tests using non-glibc C libraries e.g. musl (From OE-Core rev: 5f1895fb94d35a1496f22863791ad6f7a6aca97a) Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

4Subject: [PATCH] include linux/stddef.h in swab.h uapi header
5
6swab.h uses __always_inline without including the header where it is
7defined, this is exposed by musl based distributions where this macro is
8not defined by system C library headers unlike glibc where it is defined
9in sys/cdefs.h and that header gets pulled in indirectly via
10
11features.h -> sys/cdefs.h
12
13and features.h gets pulled in a lot of headers. Therefore it may work in
14cases where features.h is includes but not otherwise.
15
16Adding linux/stddef.h here ensures that __always_inline is always
17defined independent of which C library is used in userspace
