Hi,
The v2 renames set_selection() and do_set_selection() to following
more explicit names:
set_selection_user() /* includes copying data from user space */
set_selection_kernel() /* no copying from user space */
The patches also update references to set_selection() to be
forever.

Speakup's selection functionality parallels that of
drivers/tty/vt/selection.c. This patch set replaces speakup's
implementation with calls to vt's selection code. This is one of the
remaining items in our TODO file and it's needed for moving speakup out

This patch uses json's {} and [] to imply struct/union and array. More
explicit information can be added later. For example, a command line
option can be introduced to print whether a key or value is struct
or union, name of a struct etc. This will however come at the expense
of duplicating info
mper introduced in previous patch to accomplish
the above. Indeed, btf-ful info is only displayed if btf data for the
given map is available. Otherwise existing output is displayed as-is.

When TTY is not built, tty_kopen should return an error. This way
calling code remains consistent, regardless of whether tty is built or
not. This patch returns -ENODEV when there is no tty.

I have
tested this with minicom, picocom and commands like "echo foo >
/dev/ttyS0". They all correctly report "Device or resource busy" when
the tty is already kernel opened.

Since we have tty_kopen, we no longer need to export tty_open_by_driver.
This patch makes this function static.
