Subject: Question about the dependency on the config SOC_FSL in CPM_QMC

Dear Herve,

In your patch below, you added the config CPM_QMC which depends on the
non-existing config SOC_FSL:

https://lore.kernel.org/r/[email protected]

Up to my knowledge, the config SOC_FSL never existed in the mainline
tree. Is this dependency really required or can the expression simply
be reduced to COMPILE_TEST and we drop the dependency to SOC_FSL?

Note: This patch has now shown up in linux-next with commit
3178d58e0b97. Currently, it would not be possible to compile test this
driver, as the dependency on SOC_FSL is never met.


Best regards,

Lukas

My bad :(

The dependency must be FSL_SOC instead of SOC_FSL.
I mean:
diff --git a/drivers/soc/fsl/qe/Kconfig b/drivers/soc/fsl/qe/Kconfig
index f90cfdf0c763..7268c2fbcbc1 100644

That's a mistake, should be FSL_SOC.

Herve, are you going to send a quick fix to your patch or ask Mark if
your original patch can simply be replaced with a new one with this
change added?

I have just sent a quick fix.

Mark, it can be squashed with
3178d58e0b97 ("soc: fsl: cpm1: Add support for QMC")
