use clamp_t in UNAME26 fix
The min/max call needed to have explicit types on some architectures (e.g. mn10300). Use clamp_t instead to avoid the warning: kernel/sys.c: In function 'override_release': kernel/sys.c:1287:10: warning: comparison of distinct pointer types lacks a cast [enabled by default] Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
