The cur_item variable from keyhelp.c is an index into a table of
messages.  The following condition should always hold:
MSG_FUNCNAMES_START + cur_item <= MSG_FUNCNAMES_END.
The check in keyhelp.c was wrong.  It allowed cur_item to be
incremented to an out-of-bounds value.

We still leaked many resources when Speakup failed to initialize.
Examples of leaked resources include:
/dev/synth, keyboard or VT notifiers, and heap-allocated st_spk_t
structs.
This is fixed.

* We now use PTR_ERR to detect kthread_create failure
(thank you Dan Carpenter).

* The loop which frees members of the speakup_console array now iterates
over the whole array, not stopping at the first NULL value.  Fixes
a possible memory leak.  Safe because kfree(NULL) is a no-op.

* The order of some initializations was changed.  The safe ones, which
will never fail, are performed first.

Fix up trivial conflict in drivers/video/udlfb.c

fix the failure handling in kobjects and the main function so that we
release the virtual keyboard if we exit due to another failure.

The whole function can be expressed as a simple this_cpu_read() operation.
The function overhead is now likely multiple times that of the single
instruction that is executed in it.

Sedat: fixed compile failure caused by an extra ')'.
