4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Javier Martinez Canillas <[email protected]> commit 34b89b2967f284937be6759936ef3dc4d3aff2d0 upstream. If the driver is built as a module, autoload won't work because the module alias information is not filled. 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 <[email protected]> Reviewed-by: Krzysztof Kozlowski <[email protected]> Tested-by: Krzysztof Kozlowski <[email protected]> Signed-off-by: Stephen Boyd <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- drivers/clk/samsung/clk-exynos-audss.c | 1 + 1 file changed, 1 insertion(+) --- a/drivers/clk/samsung/clk-exynos-audss.c +++ b/drivers/clk/samsung/clk-exynos-audss.c @@ -82,6 +82,7 @@ static const struct of_device_id exynos_ .data = (void *)TYPE_EXYNOS5420, }, {}, }; +MODULE_DEVICE_TABLE(of, exynos_audss_clk_of_match); static void exynos_audss_clk_teardown(void) {
