Since commit e45d1c80c0ee ("gpio: put GPIO IRQs into their own lock
class") and commit a0a8bcf4670c ("gpiolib: irqchip: use different
lockdep class for each gpio irqchip") GPIO lib takes care of lockdep
classes. In fact, gpiochip_irq_map() overwrites the class anyway, so
the lockdep class set by the driver is useless. Remove it.Signed-off-by: Stefan Agner <[email protected]> --- drivers/gpio/gpio-tegra.c | 9 --------- 1 file changed, 9 deletions(-) diff --git a/drivers/gpio/gpio-tegra.c b/drivers/gpio/gpio-tegra.c index 94396caaca75..e5fcc012179e 100644 --- a/drivers/gpio/gpio-tegra.c +++ b/drivers/gpio/gpio-tegra.c @@ -550,13 +550,6 @@ static const struct dev_pm_ops tegra_gpio_pm_ops = { SET_SYSTEM_SLEEP_PM_OPS(tegra_gpio_suspend, tegra_gpio_resume) }; -/* - * This lock class tells lockdep that GPIO irqs are in a different category - * than their parents, so it won't report false recursion. - */ -static struct lock_class_key gpio_lock_class; -static struct lock_class_key gpio_request_class; - static int tegra_gpio_probe(struct platform_device *pdev) { struct tegra_gpio_info *tgi; @@ -661,8 +654,6 @@ static int tegra_gpio_probe(struct platform_device *pdev) bank = &tgi->bank_info[GPIO_BANK(gpio)]; - irq_set_lockdep_class(irq, &gpio_lock_class, - &gpio_request_class); irq_set_chip_data(irq, bank); irq_set_chip_and_handler(irq, &tgi->ic, handle_simple_irq); } -- 2.18.0
