In spk_ttyio_release we read tty's index but never do anything with it.
The patch removes this dead code.

We should check the flush_buffer method of a tty for null before
invoking it. Some drivers such as usbserial don't implement
flush_buffer. This will be required for upcoming patches where we expand
spk_ttyio to support more than just ttyS*.

lib-move.c file has a lot of expressions in the form of:

Clean up the helper functions used to implement "dump_granted_max" in
debugfs.

Replace the lprocfs_rd_uint() and lprocfs_wr_uint() generic callbacks
with a simpler, more direct implementation of ldlm_rw_uint_fops.

There's a slight change in lustre debugfs write semantics: Using kstrtox
causes EINVAL when the written number is followed by other (garbage)
characters, whereas previously the garbage would be ignored and such a
write would succeed.
