From: Shrirang Bagul Date: Wed, 19 Apr 2017 14:05:00 +0000 (+0800) Subject: iio: st_pressure: st_accel: Initialise sensor platform data properly X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7383d44b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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 --- diff --git a/drivers/iio/accel/st_accel_core.c b/drivers/iio/accel/st_accel_core.c index 784670e2736b..07d1489cd457 100644 --- a/drivers/iio/accel/st_accel_core.c +++ b/drivers/iio/accel/st_accel_core.c @@ -710,6 +710,8 @@ static const struct iio_trigger_ops st_accel_trigger_ops = { int st_accel_common_probe(struct iio_dev *indio_dev) { struct st_sensor_data *adata = iio_priv(indio_dev); + struct st_sensors_platform_data *pdata = + (struct st_sensors_platform_data *)adata->dev->platform_data; int irq = adata->get_irq_data_ready(indio_dev); int err; @@ -736,9 +738,8 @@ int st_accel_common_probe(struct iio_dev *indio_dev) &adata->sensor_settings->fs.fs_avl[0]; adata->odr = adata->sensor_settings->odr.odr_avl[0].hz; - if (!adata->dev->platform_data) - adata->dev->platform_data = - (struct st_sensors_platform_data *)&default_accel_pdata; + if (!pdata) + pdata = (struct st_sensors_platform_data *)&default_accel_pdata; err = st_sensors_init_sensor(indio_dev, adata->dev->platform_data); if (err < 0) 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)
