Char/Misc bugfix for 6.10-rc1

Browse Source 
Here is one remaining bugfix for 6.10-rc1 that missed the 6.9-final
 merge window, and has been sitting in my tree and linux-next for quite a
 while now, but wasn't sent to you (my fault, travels...)
 
 It is a bugfix to resolve an error in the speakup code that could
 overflow a buffer.
 
 It has been in linux-next for a while with no reported problems.
