ae6385af37 braille_console: remove MODULE_LICENSE in non-modules
Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

5abbeebd82 tty: fix possible null-ptr-defer in spk_ttyio_release
Run the following tests on the qemu platform:

syzkaller:~# modprobe speakup_audptr

spk_ttyio_initialise_ldisc failed because tty_kopen_exclusive returned
failed (errno -16), then remove the module, we will get a null-ptr-defer

72b8ec15f9 accessibility: speakup: phonetic spelling while arrowing letter by letter
This patch includes an enhancement requested frequently on the mailing
list.[1][2] It adds a variable, cur_phonetic in the spk_vars, which can
be set as a module parameter, as well as in /sys/speakup/cur_phonetic.
This patch also documents cur_phonetic as a sysfs attribute in
sysfs-driver-speakup.

When cur_phonetic=1, it causes speakup to speak letters phonetically if
paused on the character while arrowing through a word.

When a user does not set cur_phonetic to any value, the default value
for it would be 0.

0fc801f801 speakup: fix a segfault caused by switching consoles
This patch fixes a segfault by adding a null check on synth in
speakup_con_update(). The segfault can be reproduced as follows:

	- Login into a text console

	- Load speakup and speakup_soft modules

	- Remove speakup_soft

	- Switch to a graphics console

This is caused by lack of a null check on `synth` in
speakup_con_update().

Here's the sequence that causes the segfault:

	- When we remove the speakup_soft, synth_release() sets the synth
	  to null.

	- After that, when we change the virtual console to graphics
	  console, vt_notifier_call() is fired, which then calls
	  speakup_con_update().

	- Inside speakup_con_update() there's no null check on synth,
	  so it calls synth_printf().

	- Inside synth_printf(), synth_buffer_add() and synth_start(),
	  both access synth, when it is null and causing a segfault.

Therefore adding a null check on synth solves the issue.
