From b52fabca369f433999837b73031bdd34feb6fca2 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 24 Nov 2011 10:29:14 -0500 Subject: [PATCH 1/2] hwmon: Remove redundant spi driver bus initialization In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_register_driver(), so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // Signed-off-by: Lars-Peter Clausen Cc: Jean Delvare Cc: Guenter Roeck Cc: lm-sensors@lm-sensors.org Signed-off-by: Guenter Roeck --- drivers/hwmon/ad7314.c | 1 - drivers/hwmon/ads7871.c | 1 - 2 files changed, 2 deletions(-) diff --git a/drivers/hwmon/ad7314.c b/drivers/hwmon/ad7314.c index 318e38e8537..5d760f3d21c 100644 --- a/drivers/hwmon/ad7314.c +++ b/drivers/hwmon/ad7314.c @@ -160,7 +160,6 @@ MODULE_DEVICE_TABLE(spi, ad7314_id); static struct spi_driver ad7314_driver = { .driver = { .name = "ad7314", - .bus = &spi_bus_type, .owner = THIS_MODULE, }, .probe = ad7314_probe, diff --git a/drivers/hwmon/ads7871.c b/drivers/hwmon/ads7871.c index 52319340e18..04450f8bf5d 100644 --- a/drivers/hwmon/ads7871.c +++ b/drivers/hwmon/ads7871.c @@ -227,7 +227,6 @@ static int __devexit ads7871_remove(struct spi_device *spi) static struct spi_driver ads7871_driver = { .driver = { .name = DEVICE_NAME, - .bus = &spi_bus_type, .owner = THIS_MODULE, }, From 25a236a5dba47a16affb105525cfd75eaa03ceea Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 25 Nov 2011 02:31:00 -0500 Subject: [PATCH 2/2] hwmon: convert drivers/hwmon/* to use module_platform_driver() This patch converts the drivers in drivers/hwmon/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.
