[PATCH 1/3] auxdisplay: ht16k33: do not try to free fbdev

[Dmitry Torokhov]

'fbdev' is allocated as part of larger ht16k33_priv structure; trying to
free it will cause troubles.

Note that the patches have not been tried on a real hardware.

I am pretty confident in #1 and #3, but #2 is larger and it would be great
if someone with hardware tried running it before it gets applied.

Thanks!
