[PATCH 03/10] tty: hvsi: remove an extra variable from hvsi_write()

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

'source' is the same as 'buf'. Rename the parameter ('buf') to
'source' and drop the local variable.

Likely, the two were introduced to have a different type. But 'char' and
'unsigned char' are the same in the kernel for a long time.
