From 8f97f8e58bd385d3c863a0437eae21a3ca7cc5d8 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Mon, 25 Jul 2016 13:47:52 -0700 Subject: [PATCH] Input: cros_ec_keyb - cleanup use of dev In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was the EC's dev pointer and not the keyboard's. Let's clean this up to make it the keyboard's dev pointer. This could be useful in future patches but also has the nice effect of changing a few printouts to include the name of the keyboard device instead of the EC device, so we will see: [ 1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14 instead of: [ 1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14 Signed-off-by: Douglas Anderson Signed-off-by: Brian Norris Signed-off-by: Dmitry Torokhov --- drivers/input/keyboard/cros_ec_keyb.c | 19 +++++++++---------- 1 file changed, 9 insertions(+), 10 deletions(-) diff --git a/drivers/input/keyboard/cros_ec_keyb.c b/drivers/input/keyboard/cros_ec_keyb.c index b01966dc7eb3..4b0878f35471 100644 --- a/drivers/input/keyboard/cros_ec_keyb.c +++ b/drivers/input/keyboard/cros_ec_keyb.c @@ -186,7 +186,7 @@ static irqreturn_t cros_ec_keyb_irq(int irq, void *data) if (ret >= 0) cros_ec_keyb_process(ckdev, kb_state, ret); else - dev_err(ec->dev, "failed to get keyboard state: %d\n", ret); + dev_err(ckdev->dev, "failed to get keyboard state: %d\n", ret); return IRQ_HANDLED; } @@ -236,7 +236,7 @@ static void cros_ec_keyb_compute_valid_keys(struct cros_ec_keyb *ckdev) static int cros_ec_keyb_probe(struct platform_device *pdev) { struct cros_ec_device *ec = dev_get_drvdata(pdev->dev.parent); - struct device *dev = ec->dev; + struct device *dev = &pdev->dev; struct cros_ec_keyb *ckdev; struct input_dev *idev; struct device_node *np; @@ -246,23 +246,22 @@ static int cros_ec_keyb_probe(struct platform_device *pdev) if (!np) return -ENODEV; - ckdev = devm_kzalloc(&pdev->dev, sizeof(*ckdev), GFP_KERNEL); + ckdev = devm_kzalloc(dev, sizeof(*ckdev), GFP_KERNEL); if (!ckdev) return -ENOMEM; - err = matrix_keypad_parse_of_params(&pdev->dev, &ckdev->rows, - &ckdev->cols); + err = matrix_keypad_parse_of_params(dev, &ckdev->rows, &ckdev->cols); if (err) return err; - ckdev->valid_keys = devm_kzalloc(&pdev->dev, ckdev->cols, GFP_KERNEL); + ckdev->valid_keys = devm_kzalloc(dev, ckdev->cols, GFP_KERNEL); if (!ckdev->valid_keys) return -ENOMEM; - ckdev->old_kb_state = devm_kzalloc(&pdev->dev, ckdev->cols, GFP_KERNEL); + ckdev->old_kb_state = devm_kzalloc(dev, ckdev->cols, GFP_KERNEL); if (!ckdev->old_kb_state) return -ENOMEM; - idev = devm_input_allocate_device(&pdev->dev); + idev = devm_input_allocate_device(dev); if (!idev) return -ENOMEM; @@ -273,7 +272,7 @@ static int cros_ec_keyb_probe(struct platform_device *pdev) ckdev->ec = ec; ckdev->dev = dev; - dev_set_drvdata(&pdev->dev, ckdev); + dev_set_drvdata(dev, ckdev); idev->name = CROS_EC_DEV_NAME; idev->phys = ec->phys_name; @@ -282,7 +281,7 @@ static int cros_ec_keyb_probe(struct platform_device *pdev) idev->id.bustype = BUS_VIRTUAL; idev->id.version = 1; idev->id.product = 0; - idev->dev.parent = &pdev->dev; + idev->dev.parent = dev; idev->open = cros_ec_keyb_open; idev->close = cros_ec_keyb_close;
