Function pmc_core_slps0_display() is responsible for displaying debug
registers, which is under CONFIG_DEBUG_FS.
Providing the static inline stub whenever CONFIG_DEBUG_FS is disabled
to fix this. Function pmc_core_lpm_display() is the same.

Thank you for the patch, but I think it's not the right approach.
Basically we need to move those functions outside of #if
IS_ENABLED(CONFIG_DEBUG_FS).
(Move them upper).
Also I have noticed another issue in pmc_core_lpm_display(). It uses
tgl_lpm_maps directly. It shouldn't.

Gayatri, care to fix?

Update: Andy, I have 4 small fixes for the patch series merged in for-next branch. I am wondering if I should send the fixup patches or if you drop the patch series from for-next branch, I can send out the new version that includes all these fixes. Please suggest. Thanks!

I don't see it in the mailing list.
Please check if you send them correctly.
There are more bug reports coming. We must fix this ASAP.
