isdn/capi warning fixes
drivers/isdn/capi/capi.c: In function 'handle_minor_send':
drivers/isdn/capi/capi.c:552: warning: cast from pointer to integer of
different size
Of course, the code here might actually be buggy, in which case this patch
should not be applied?
Answer:
No this field is ignored inside linux kernel.Yes this is ugly, but it's
the CAPI spec for all OS.
CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which
represent the 32 bit buffer address of the payload data. In linux the
payload data do not use a sperate buffer, data follows directely after the
CAPI Message in the same skb and we use this assumption inside the
drivers,
so we can ignore this field.
Inside the linux CAPI implemetation we never use this field, so it could
also have no value, but since random data in a message is bad as well
(e.g.
displayed in CAPI traces) we set is to the most adequate value.
Outside the kernel the capi20 library sets the correct addresses (there is
an optional second field for 64 bit adresses for 64 bit systems, we do not
use here).
