[PATCH] powerpc32: fix warning from include/asm-generic/termios-base.h

[Christophe Leroy]

When size is equal to 1, the test is always true so lets eliminate both 0 and 1
at first.

include/asm-generic/termios-base.h: In function 'user_termio_to_kernel_termios':
include/asm-generic/termios-base.h:35:2: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]
  if (get_user(termios->c_line, &termio->c_line) < 0)
  ^

      put_user(termios->c_line,  &termio->c_line) < 0 ||
