[PATCH v2 2/5] linux ttyname: Update a reference to kernel docs for kernel 4.10

[Luke Shumaker]

Linux 4.10 moved many of the documentation files around.

It came out between the time the patch adding the comment (commit
15e9a4f3) was submitted and the time it was applied (in February,
January, and March 2017; respectively).
