Subject: Re: [PATCH] cdx: Fix atomicity violation in cdx_bus_match() and cdx_probe()

Hello,

We have addressed the concurrency issue in the match driver interface
at a higher level, as detailed in the
[https://lore.kernel.org/all/20241112163041.40083-1-chenqiuji666@gmail.com/].
Due to the widespread nature of the issue, it is more appropriate to
resolve it by adding a lock at the higher level.

Therefore, in v2, we have removed the changes to the cdx_bus_match()
function, as the higher-level fix conflicts with those changes.

Kindly refrain from merging the v1 of this patch. Thank you.

Regards,
Qiu-ji Chen
