Seems ath11k driver base here on ath11k-$(CONFIG_THERMAL) += thermal.o
So, probably you should add ATH11K_CONFIG_THERMAL and send to linux-wireless ...

I only have PCI version and really need smth that will at least build
after will check kmod-ath11k.
Don't see any problem to fix it later - similar like we have in ath10k
- should be easy to do.

Now I think will focus on adding this series, while my platform don't
support 32 MSI vectors (not sure why we don't have them in 5.15):

Carl Huang (6):
   ath11k: get msi_data again after request_irq is called
   ath11k: add ce and ext irq flag to indicate irq_handler
   ath11k: use ATH11K_PCI_IRQ_DP_OFFSET for dp irqx
   ath11k: refactor mulitple msi vector implementation
   ath11k: supports one MSI vector
   ath11k: do not restore ASPM in case of single MSI vector

BTW, probably we should also resend:
https://patchwork.kernel.org/project/linux-arm-msm/patch/20180427140358.30839-1-elder@linaro.org/
While we have real reason to unlock QCOM_QMI_HELPERS.

Regarding ath.mk patch - this is base on Hauke patch - probably we
should change author here :)
