From mboxrd@z Thu Jan 1 00:00:00 1970 From: Javier Martinez Canillas Subject: [PATCH 4/4] spi: ath79: Fix module autoload for OF registration Date: Wed, 23 Nov 2016 13:37:11 -0300 Message-ID: <1479919031-5112-5-git-send-email-javier@osg.samsung.com> References: <1479919031-5112-1-git-send-email-javier@osg.samsung.com> Cc: Javier Martinez Canillas , Mark Brown , linux-spi@vger.kernel.org To: linux-kernel@vger.kernel.org Return-path: In-Reply-To: <1479919031-5112-1-git-send-email-javier@osg.samsung.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-spi.vger.kernel.org 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/spi/spi-ath79.ko | grep alias alias: platform:ath79-spi After this patch: $ modinfo drivers/spi/spi-ath79.ko | grep alias alias: platform:ath79-spi alias: of:N*T*Cqca,ar7100-spiC* alias: of:N*T*Cqca,ar7100-spi Signed-off-by: Javier Martinez Canillas --- drivers/spi/spi-ath79.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/spi/spi-ath79.c b/drivers/spi/spi-ath79.c index 6165bf21d427..f369174fbd88 100644 --- a/drivers/spi/spi-ath79.c +++ b/drivers/spi/spi-ath79.c @@ -304,6 +304,7 @@ static const struct of_device_id ath79_spi_of_match[] = { { .compatible = "qca,ar7100-spi", }, { }, }; +MODULE_DEVICE_TABLE(of, ath79_spi_of_match); static struct platform_driver ath79_spi_driver = { .probe = ath79_spi_probe, -- 2.7.4
