From 8d6c16dd7213fa43702416e3dd1059e9e36bc758 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sat, 5 Dec 2015 16:23:26 +0000 Subject: [PATCH] iio:configfs: Introduce iio/configfs.h to provide a location for the configfs_subsystem This exported element needs to be accesible to all drivers using configfs within IIO. Previously it was in the sw_trig.h file which only convered one such usecase. This also fixes a sparse warning as it is now in a header that makes sense to include from industrialio-configfs.c Signed-off-by: Jonathan Cameron < jic23@kernel.org> --- drivers/iio/industrialio-configfs.c | 1 + drivers/iio/industrialio-sw-trigger.c | 1 + include/linux/iio/configfs.h | 15 +++++++++++++++ include/linux/iio/sw_trigger.h | 1 - 4 files changed, 17 insertions(+), 1 deletion(-) create mode 100644 include/linux/iio/configfs.h diff --git a/drivers/iio/industrialio-configfs.c b/drivers/iio/industrialio-configfs.c index 83563dd7fcf4..45ce2bc47180 100644 --- a/drivers/iio/industrialio-configfs.c +++ b/drivers/iio/industrialio-configfs.c @@ -15,6 +15,7 @@ #include #include +#include static struct config_item_type iio_root_group_type = { .ct_owner = THIS_MODULE, diff --git a/drivers/iio/industrialio-sw-trigger.c b/drivers/iio/industrialio-sw-trigger.c index 4825cfd9c4ea..311f9fe5aa34 100644 --- a/drivers/iio/industrialio-sw-trigger.c +++ b/drivers/iio/industrialio-sw-trigger.c @@ -15,6 +15,7 @@ #include #include +#include #include static struct config_group *iio_triggers_group; diff --git a/include/linux/iio/configfs.h b/include/linux/iio/configfs.h new file mode 100644 index 000000000000..93befd67c15c --- /dev/null +++ b/include/linux/iio/configfs.h @@ -0,0 +1,15 @@ +/* + * Industrial I/O configfs support + * + * Copyright (c) 2015 Intel Corporation + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License version 2 as published by + * the Free Software Foundation. + */ +#ifndef __IIO_CONFIGFS +#define __IIO_CONFIGFS + +extern struct configfs_subsystem iio_configfs_subsys; + +#endif /* __IIO_CONFIGFS */ diff --git a/include/linux/iio/sw_trigger.h b/include/linux/iio/sw_trigger.h index c2f33b2b35a5..5198f8ed08a4 100644 --- a/include/linux/iio/sw_trigger.h +++ b/include/linux/iio/sw_trigger.h @@ -20,7 +20,6 @@ module_driver(__iio_sw_trigger_type, iio_register_sw_trigger_type, \ iio_unregister_sw_trigger_type) -extern struct configfs_subsystem iio_configfs_subsys; struct iio_sw_trigger_ops; struct iio_sw_trigger_type { -- 2.20.1
