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/20230217145645.1768659-7-herve.codina@xxxxxxxxxxx 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
