Cmnt: [SRU][I][PATCH 0/1] crypto: hisilicon/qm - modify the uacce mode check

[Taihsiang Ho (tai271828)]

Thanks Tim and Stefan[1] for your comments.

May we land the patch for Jammy as well? I elaborated the rationale and the
verification of the corresponding Test Plan for Jammy in the same BugLink
https://bugs.launchpad.net/bugs/1933301 (see the latest comment, which is
comment#42).

Let me know if I need to create a new email thread to include [J] for you
to manage the patch-landing flow easier. I am glad to create a new thread
if needed. Thanks.
