So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/char/hw_random/meson-rng.ko | grep alias alias: platform:meson-rng After this patch: $ modinfo drivers/char/hw_random/meson-rng.ko | grep alias alias: platform:meson-rng alias: of:N*T*Camlogic,meson-rngC* alias: of:N*T*Camlogic,meson-rng Signed-off-by: Javier Martinez Canillas --- drivers/char/hw_random/meson-rng.c | 1 + drivers/char/tpm/Kconfig | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/char/hw_random/meson-rng.c b/drivers/char/hw_random/meson-rng.c index 58bef39f7286..51864a509be7 100644 --- a/drivers/char/hw_random/meson-rng.c +++ b/drivers/char/hw_random/meson-rng.c @@ -110,6 +110,7 @@ static const struct of_device_id meson_rng_of_match[] = { { .compatible = "amlogic,meson-rng", }, {}, }; +MODULE_DEVICE_TABLE(of, meson_rng_of_match); static struct platform_driver meson_rng_driver = { .probe = meson_rng_probe, diff --git a/drivers/char/tpm/Kconfig b/drivers/char/tpm/Kconfig index 9faa0b1e7766..982ed2fe927c 100644 --- a/drivers/char/tpm/Kconfig +++ b/drivers/char/tpm/Kconfig @@ -32,7 +32,7 @@ config TCG_TIS_CORE config TCG_TIS tristate "TPM Interface Specification 1.2 Interface / TPM 2.0 FIFO Interface" - depends on X86 + depends on X86 || COMPILE_TEST select TCG_TIS_CORE ---help--- If you have a TPM security chip that is compliant with the -- 2.7.4
