Signed-off-by: Maíra Canal --- I apologize if you received this email more than once. For some reason, the patch is not showing up on the linux-iio mailing list. I believe that the problem was that Michael's Hennerich email on the MAINTAINERS list was Michael.Hennerich@analog.com instead of michael.hennerich@analog.com. Anyway, I am truly sorry with you received this email more than once. --- drivers/iio/adc/ad7266.c | 43 +++++++++++++--------------------------- 1 file changed, 14 insertions(+), 29 deletions(-) diff --git a/drivers/iio/adc/ad7266.c b/drivers/iio/adc/ad7266.c index c17d9b5fbaf6..4f8f07d5c1a3 100644 --- a/drivers/iio/adc/ad7266.c +++ b/drivers/iio/adc/ad7266.c @@ -378,6 +378,11 @@ static const char * const ad7266_gpio_labels[] = { "ad0", "ad1", "ad2", }; +static void ad7266_reg_disable(void *reg) +{ + regulator_disable(reg); +} + static int ad7266_probe(struct spi_device *spi) { struct ad7266_platform_data *pdata = spi->dev.platform_data; @@ -398,9 +403,13 @@ static int ad7266_probe(struct spi_device *spi) if (ret) return ret; + ret = devm_add_action_or_reset(&spi->dev, ad7266_reg_disable, st->reg); + if (ret) + return ret; + ret = regulator_get_voltage(st->reg); if (ret < 0) - goto error_disable_reg; + return ret; st->vref_mv = ret / 1000; } else { @@ -423,7 +432,7 @@ static int ad7266_probe(struct spi_device *spi) GPIOD_OUT_LOW); if (IS_ERR(st->gpios[i])) { ret = PTR_ERR(st->gpios[i]); - goto error_disable_reg; + return ret; } } } @@ -459,35 +468,12 @@ static int ad7266_probe(struct spi_device *spi) spi_message_add_tail(&st->single_xfer[1], &st->single_msg); spi_message_add_tail(&st->single_xfer[2], &st->single_msg); - ret = iio_triggered_buffer_setup(indio_dev, &iio_pollfunc_store_time, + ret = devm_iio_triggered_buffer_setup(&spi->dev, indio_dev, &iio_pollfunc_store_time, &ad7266_trigger_handler, &iio_triggered_buffer_setup_ops); if (ret) - goto error_disable_reg; - - ret = iio_device_register(indio_dev); - if (ret) - goto error_buffer_cleanup; - - return 0; - -error_buffer_cleanup: - iio_triggered_buffer_cleanup(indio_dev); -error_disable_reg: - if (!IS_ERR(st->reg)) - regulator_disable(st->reg); - - return ret; -} - -static void ad7266_remove(struct spi_device *spi) -{ - struct iio_dev *indio_dev = spi_get_drvdata(spi); - struct ad7266_state *st = iio_priv(indio_dev); + return ret; - iio_device_unregister(indio_dev); - iio_triggered_buffer_cleanup(indio_dev); - if (!IS_ERR(st->reg)) - regulator_disable(st->reg); + return devm_iio_device_register(&spi->dev, indio_dev); } static const struct spi_device_id ad7266_id[] = { @@ -502,7 +488,6 @@ static struct spi_driver ad7266_driver = { .name = "ad7266", }, .probe = ad7266_probe, - .remove = ad7266_remove, .id_table = ad7266_id, }; module_spi_driver(ad7266_driver); -- 2.35.1
