Two update suggestions were taken into account
from static source code analysis.

[PATCH 1/2] ipack: Delete an error message for a failed memory allocation in ipack_device_read_id()

Omit an extra message for a memory allocation failure in this function.

This issue was detected by using the Coccinelle software.

[PATCH 2/2] ipack: Improve a size determination in ipack_bus_register()

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

I'm sorry, but this person is in my blacklist and I don't have any of
their emails, so I don't have these patches anywhere.  If you wish to
have them applied, please resend them with your acked-by, or just ignore
them, it's up to you.

good luck!

Some developers know this communication setting in the meantime.

I find this kind of feedback inappropriate.

You chose to exclude my update suggestions at a specific point in time.
They are still publicly available as they were stored also by other
information systems despite my messages vanish from your personal mail in-box
for a while.

I am curious how other contributors will think about the shown change patterns.


> or just ignore them, it's up to you.

This reaction is also a possible option depending on your development priorities
for the affected software modules.

I hope that remaining open issues can be improved as desired after a bit of
constructive software development discussion.

Regards,
Markus
