Subject: tools/nolibc: remove outdated comment about __sysret() in mmap()
X-Git-Tag: v6.19-rc1~194^2~22

tools/nolibc: remove outdated comment about __sysret() in mmap()

Since commit fb01ff635efd ("tools/nolibc: keep brk(), sbrk(), mmap()
away from __sysret()") the implementation of mmap() does not use the
__sysret() macro anymore.

Remove the outdated comment.
