Re: [PATCH] ser_a2232.c bug removed: handles "IRQ request denied" case

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Well... I realize there's no point in fixing things which I cannot
even see going wrong: I cannot get hold of another A2232 after the
one I had used before went missing.

So until someone contacts me to supply me with a A2232 card, this
driver is an "Orphan" now, sorry.

Changed "Orphaned" to "Orphan", as this is the official "S:" value.

Patch is against Linux-2.6.23.1 .
