From 78856ac0dd33036ae08a18b644e9fa40b30ee011 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 5 Oct 2015 13:07:47 +0200 Subject: Revert "gpio-sysfs: Use gpio descriptor name instead of gpiochip names array" This reverts commit ddd5404007b8496f20ad2efe1147e102e6226634. We need to preserve only using this naming strategy for names coming from chip->names[], the descripor->name field is for the new interface. --- drivers/gpio/gpiolib-sysfs.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/gpio/gpiolib-sysfs.c b/drivers/gpio/gpiolib-sysfs.c index 3e81f28e3aee..b57ed8e55ab5 100644 --- a/drivers/gpio/gpiolib-sysfs.c +++ b/drivers/gpio/gpiolib-sysfs.c @@ -550,7 +550,9 @@ int gpiod_export(struct gpio_desc *desc, bool direction_may_change) struct gpiod_data *data; unsigned long flags; int status; + const char *ioname = NULL; struct device *dev; + int offset; /* can't export until sysfs is available ... */ if (!gpio_class.p) { @@ -599,9 +601,13 @@ int gpiod_export(struct gpio_desc *desc, bool direction_may_change) else data->direction_can_change = false; + offset = gpio_chip_hwgpio(desc); + if (chip->names && chip->names[offset]) + ioname = chip->names[offset]; + dev = device_create_with_groups(&gpio_class, chip->dev, MKDEV(0, 0), data, gpio_groups, - desc->name ? desc->name : "gpio%u", + ioname ? ioname : "gpio%u", desc_to_gpio(desc)); if (IS_ERR(dev)) { status = PTR_ERR(dev); -- cgit v1.2.3
