Thank you for the review, and thanks Gokul for the detailed
explanation - that is exactly what I meant, and sorry the annotation
was not clearer. To summarize: 43752 support has been present since
v5.15 (commit d2587c57ffd8 ("brcmfmac: add 43752 SDIO ids and
initialization")), under the SDIO_DEVICE_ID_BROADCOM_CYPRESS_43752 id
name. Commit 74e2ef72bd4b ("wifi: brcmfmac: fix 43752 SDIO FWVID
incorrectly labelled as Cypress (CYW)"), which landed in v6.18,
renamed it to SDIO_DEVICE_ID_BROADCOM_43752.

I also have to correct myself here: the boundary in the annotation
should have been "<= 6.17" rather than "<= 6.16", since the rename
only landed in v6.18. Apologies for the extra confusion.

Gokul's suggestion of cherry-picking the rename patch together with
this one into the stable trees sounds cleaner to me than editing the
id name while backporting, so I would be glad to go with that.

If it helps, I would be happy to send a v2 with the stable annotation
in the prerequisite format from
Documentation/process/stable-kernel-rules.rst:

  Cc: <stable@xxxxxxxxxxxxxxx> # 74e2ef72bd4b: wifi: brcmfmac: fix 43752 SDIO FWVID incorrectly labelled as Cypress (CYW)

Please let me know if you would prefer that, or if the patch is fine
to take as is.

Best regards,
LiangCheng
