I think this patch depends on another patchset or oppositely.
Please point that out for reviewers.

Hi Ping-Ke,

There are no dependencies for this smaller individual series other
than Linux 6.2-rc1 (as this has USB support). I made sure to not
include any of the SDIO changes in this series.
The idea is that it can be applied individually and make it either
into 6.2-rc2 (or newer) or -next (6.3).


Best regards,
Martin

BTW wireless-next or wireless-testing are the preferred baselines for
wireless patches. Of course you can use other trees if you really want,
but please try to make sure they apply to wireless-next. Conflicts are
always extra churn I would prefer to avoid.

I thought this could depend on SDIO patchset, because you add
struct for efuse layout nearby, so there may be merge conflicts.
Please ignore this comment, then.
