It looks to me like this patch needs to go to stable?

Also, the Fixes tag should probably be:

Fixes: 27450653f1db ("drivers: edac: Add EDAC driver support for QCOM SoCs")

Yes, no?

Also, please explain to me how you've tested this patch if it doesn't
even build?!

ERROR: modpost: "__devm_regmap_init_mmio_clk" [drivers/soc/qcom/llcc-qcom.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:126: Module.symvers] Error 1
make: *** [Makefile:1944: modpost] Error 2

I guess because CONFIG_QCOM_LLCC is =y in your config while I have
CONFIG_QCOM_LLCC=m.

And I reported the same build error to you the last time. Did you not
see it?

For the next version, you'd need to fix all possible Kconfig build
errors before sending.
