6.9-rc kernel wifi not working - here is the fix

[jcdutton]

Hi,

The following patch fixes 6.9-rc not working with the mt7915e driver.

From: Ben Greear <[greearb@candelatech.com](mailto:greearb@candelatech.com)>

Looks like this was missed in the initial patch that made
the conversion to the emulated chanctx drivers.

Fixes: commit 0a44dfc07074 ("wifi: mac80211: simplify non-chanctx drivers")

Signed-off-by: Ben Greear <[greearb@candelatech.com](mailto:greearb@candelatech.com)>

thx, have you send the patch to ML?

[jcdutton]

I found the patch on the linux-wireless@vger.kernel.org mailing list, and noticed it was not in your 6.9-rc tree, and thus the BPI-R3 wifi was not working.

Ok,then it is already sent...have you the patchwork-link?

My tree also misses some patches for r4 i currently collect.
