Jens -
Sorry for trouble. I did not validated this single patch. I validated
complete patch set.
Issue is improper MACRO usage MEGASAS_IS_LOGICAL, which gives incorrect
check condition in qcmd Path.
Below is proposed fix.

Ugh... So we're completing everything immediately.
Martin - I validated whole series. Apologies for this.
Please help me to know how to fix this ? Do I need to send only fix on top
of latest commit (as posted above - MACRO definition) for this issue ?
Send a fix on top of current -git asap. The current tree is completely
broken for any megaraid user. -rc4 is no time to send in untested
patches, especially not something that claims to fix a 9 year old bug
and is marked for stable as well.
