wrong ...
think that is 7 instead of 79.

Well, it's sizeof(pointer) so either 4 or 8, but still,
what Markus proposes here is _wrong_.
You are right at this place.

Markus, do you know the script probably has a lower
style conversion defect introduction rate than you do
when doing these mechanical things.
Would it be nice if the script "checkpatch.pl" could avoid to point
such a false positive out anyhow?
checkpatch reports:

WARNING: sizeof outbuf should be sizeof(outbuf)
#56: FILE: drivers/isdn/gigaset/common.c:56:
+	size_t space = sizeof outbuf - 1;

There is nothing wrong with the report,

Please use it to verify what you are doing before
submitting more defective patches.
Do you expect a resend for this update step so that an other statement
in the function "gigaset_initdriver" would eventually be adjusted?

Regards,
Markus
