Turn 'adc128_probe()' into a full resource managed function to simplify the code. This way, the .remove function can be removed. Doing so, the only 'spi_get_drvdata()' call is removed and the corresponding 'spi_set_drvdata()' can be removed as well. Suggested-by: Alexandru Ardelean <ardeleanalex@xxxxxxxxx> Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- Compile tested only. When reviewing, pay special attention to the 'spi_set_drvdata()' call removal. I recently introduced a regression with a too aggressive cleanup like that. This patch should be applied after https://lore.kernel.org/linux-iio/f33069f0-601b-4bbb-3766-026f7a161912@xxxxxxxxxx/T/#meb792dcd6540f87d9ae041660ca4738a776e924a --- drivers/iio/adc/ti-adc128s052.c | 34 +++++++++++---------------------- 1 file changed, 11 insertions(+), 23 deletions(-) diff --git a/drivers/iio/adc/ti-adc128s052.c b/drivers/iio/adc/ti-adc128s052.c index 83c1ae07b3e9..e1afdb775100 100644 --- a/drivers/iio/adc/ti-adc128s052.c +++ b/drivers/iio/adc/ti-adc128s052.c @@ -132,6 +132,13 @@ static const struct iio_info adc128_info = { .read_raw = adc128_read_raw, }; +static void adc128_disable_regulator(void *data) +{ + struct regulator *reg = data; + + regulator_disable(reg); +} + static int adc128_probe(struct spi_device *spi) { struct iio_dev *indio_dev; @@ -151,8 +158,6 @@ static int adc128_probe(struct spi_device *spi) adc = iio_priv(indio_dev); adc->spi = spi; - spi_set_drvdata(spi, indio_dev); - indio_dev->name = spi_get_device_id(spi)->name; indio_dev->modes = INDIO_DIRECT_MODE; indio_dev->info = &adc128_info; @@ -167,29 +172,13 @@ static int adc128_probe(struct spi_device *spi) ret = regulator_enable(adc->reg); if (ret < 0) return ret; - - mutex_init(&adc->lock); - - ret = iio_device_register(indio_dev); + ret = devm_add_action_or_reset(&spi->dev, adc128_disable_regulator, adc->reg); if (ret) - goto err_disable_regulator; - - return 0; - -err_disable_regulator: - regulator_disable(adc->reg); - return ret; -} - -static int adc128_remove(struct spi_device *spi) -{ - struct iio_dev *indio_dev = spi_get_drvdata(spi); - struct adc128 *adc = iio_priv(indio_dev); + return ret; - iio_device_unregister(indio_dev); - regulator_disable(adc->reg); + mutex_init(&adc->lock); - return 0; + return devm_iio_device_register(&spi->dev, indio_dev); } static const struct of_device_id adc128_of_match[] = { @@ -231,7 +220,6 @@ static struct spi_driver adc128_driver = { .acpi_match_table = ACPI_PTR(adc128_acpi_match), }, .probe = adc128_probe, - .remove = adc128_remove, .id_table = adc128_id, }; module_spi_driver(adc128_driver); -- 2.30.2
