From 0b07609ccd48a23103881a161e49eb7a282170e7 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 26 Jul 2018 17:42:52 +0200 Subject: [PATCH] gpio: tegra: drop tegra specific GPIO lockdep classes 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.
