Enhance name_to_dev_t to handle trailing newline characters on device paths. Some inputs to name_to_dev_t may come from userspace where oftentimes a '\n' is appended to the path. Added const to the name buffer in both the function declaration and the prototype to reflect input buffer handling. By handling trailing newlines in name_to_dev_t, userspace buffers may be directly passed to name_to_dev_t without modification.
We have lib/string.c:strim() - perhaps this patch would be neater if it were to use it?
