This means that this module won't auto-load if a DT has for example has a node with a compatible "infineon,slb9670" string. In that case kmod will expect a "MODALIAS=of:N*T*Cinfineon,slb9670" uevent but instead will get a "MODALIAS=spi:slb9670", which is not present in the kernel module aliases: $ modinfo drivers/char/tpm/tpm_tis_spi.ko | grep alias alias: of:N*T*Cgoogle,cr50C* alias: of:N*T*Cgoogle,cr50 alias: of:N*T*Ctcg,tpm_tis-spiC* alias: of:N*T*Ctcg,tpm_tis-spi alias: of:N*T*Cinfineon,slb9670C* alias: of:N*T*Cinfineon,slb9670 alias: of:N*T*Cst,st33htpm-spiC* alias: of:N*T*Cst,st33htpm-spi alias: spi:cr50 alias: spi:tpm_tis_spi alias: acpi*:SMO0768:* To workaround this issue, add in the SPI device ID table all the entries that are present in the OF device ID table.
