From 45259859492812c8b700ae1d157be01a8d2babfe Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 18 Oct 2012 15:43:00 +0100 Subject: [PATCH] iio: at91_adc: Use devm_kcalloc to allocate arrays Use dev_kcalloc instead of devm_kzalloc to allocate arrays since it is semantically more appropriate. While we are at it the patch also fixes the following coccinelle warning: drivers/iio/adc/at91_adc.c:277:25-31: ERROR: application of sizeof to pointer Signed-off-by: Lars-Peter Clausen Acked-By: Maxime Ripard Signed-off-by: Jonathan Cameron --- drivers/iio/adc/at91_adc.c | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/drivers/iio/adc/at91_adc.c b/drivers/iio/adc/at91_adc.c index 2e2c9a80aa37..a9176722042f 100644 --- a/drivers/iio/adc/at91_adc.c +++ b/drivers/iio/adc/at91_adc.c @@ -123,10 +123,8 @@ static int at91_adc_channel_init(struct iio_dev *idev) idev->num_channels = bitmap_weight(&st->channels_mask, st->num_channels) + 1; - chan_array = devm_kzalloc(&idev->dev, - ((idev->num_channels + 1) * - sizeof(struct iio_chan_spec)), - GFP_KERNEL); + chan_array = devm_kcalloc(&idev->dev, idev->num_channels + 1, + sizeof(*chan_array), GFP_KERNEL); if (!chan_array) return -ENOMEM; @@ -270,9 +268,8 @@ static int at91_adc_trigger_init(struct iio_dev *idev) struct at91_adc_state *st = iio_priv(idev); int i, ret; - st->trig = devm_kzalloc(&idev->dev, - st->trigger_number * sizeof(st->trig), - GFP_KERNEL); + st->trig = devm_kcalloc(&idev->dev, st->trigger_number, + sizeof(*st->trig), GFP_KERNEL); if (st->trig == NULL) { ret = -ENOMEM; @@ -454,9 +451,8 @@ static int at91_adc_probe_dt(struct at91_adc_state *st, st->registers->trigger_register = prop; st->trigger_number = of_get_child_count(node); - st->trigger_list = devm_kzalloc(&idev->dev, st->trigger_number * - sizeof(struct at91_adc_trigger), - GFP_KERNEL); + st->trigger_list = devm_kcalloc(&idev->dev, st->trigger_number, + sizeof(*st->trigger_list), GFP_KERNEL); if (!st->trigger_list) { dev_err(&idev->dev, "Could not allocate trigger list memory.\n"); ret = -ENOMEM; -- GitLab
