From 7383d44b84c94aaca4bf695a6bd8a69f2295ef1a Mon Sep 17 00:00:00 2001 From: Shrirang Bagul Date: Wed, 19 Apr 2017 22:05:00 +0800 Subject: iio: st_pressure: st_accel: Initialise sensor platform data properly This patch fixes the sensor platform data initialisation for st_pressure and st_accel device drivers. Without this patch, the driver fails to register the sensors when the user removes and re-loads the driver. 1. Unload the kernel modules for st_pressure $ sudo rmmod st_pressure_i2c $ sudo rmmod st_pressure 2. Re-load the driver $ sudo insmod st_pressure $ sudo insmod st_pressure_i2c Signed-off-by: Jonathan Cameron Acked-by: Linus Walleij --- drivers/iio/pressure/st_pressure_core.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers/iio/pressure') diff --git a/drivers/iio/pressure/st_pressure_core.c b/drivers/iio/pressure/st_pressure_core.c index fd0edca0e656..aa61ec15c139 100644 --- a/drivers/iio/pressure/st_pressure_core.c +++ b/drivers/iio/pressure/st_pressure_core.c @@ -568,6 +568,8 @@ static const struct iio_trigger_ops st_press_trigger_ops = { int st_press_common_probe(struct iio_dev *indio_dev) { struct st_sensor_data *press_data = iio_priv(indio_dev); + struct st_sensors_platform_data *pdata = + (struct st_sensors_platform_data *)press_data->dev->platform_data; int irq = press_data->get_irq_data_ready(indio_dev); int err; @@ -603,10 +605,8 @@ int st_press_common_probe(struct iio_dev *indio_dev) press_data->odr = press_data->sensor_settings->odr.odr_avl[0].hz; /* Some devices don't support a data ready pin. */ - if (!press_data->dev->platform_data && - press_data->sensor_settings->drdy_irq.addr) - press_data->dev->platform_data = - (struct st_sensors_platform_data *)&default_press_pdata; + if (!pdata && press_data->sensor_settings->drdy_irq.addr) + pdata = (struct st_sensors_platform_data *)&default_press_pdata; err = st_sensors_init_sensor(indio_dev, press_data->dev->platform_data); if (err < 0) -- cgit v1.2.3
