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/clk/samsung/clk-exynos-audss.ko | grep alias alias: platform:exynos-audss-clk After this patch: $ modinfo drivers/clk/samsung/clk-exynos-audss.ko | grep alias alias: platform:exynos-audss-clk alias: of:N*T*Csamsung,exynos5420-audss-clockC* alias: of:N*T*Csamsung,exynos5420-audss-clock alias: of:N*T*Csamsung,exynos5410-audss-clockC* alias: of:N*T*Csamsung,exynos5410-audss-clock alias: of:N*T*Csamsung,exynos5250-audss-clockC* alias: of:N*T*Csamsung,exynos5250-audss-clock alias: of:N*T*Csamsung,exynos4210-audss-clockC* alias: of:N*T*Csamsung,exynos4210-audss-clock Fixes: 4d252fd5719b ("clk: samsung: Allow modular build of the Audio Subsystem CLKCON driver") Signed-off-by: Javier Martinez Canillas Reviewed-by: Krzysztof Kozlowski Tested-by: Krzysztof Kozlowski --- Changes in v2: - Add fixes tag.
