From 60ed54cae8dc0f2d41cafbd477bbed6deb716615 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 7 Nov 2017 19:15:57 +0100 Subject: gpio: Disambiguate struct gpio_irq_chip.nested The nested field in struct gpio_irq_chip currently has two meanings. On one hand it marks an IRQ chip as being nested (as opposed to chained), while on the other hand it also means that an IRQ chip uses nested thread handlers. However, nested IRQ chips can already be identified by the fact that they don't pass a parent handler (the driver would instead already have installed a nested handler using request_irq()). Therefore, the only use for the nested attribute is to inform gpiolib that an IRQ chip uses nested thread handlers (as opposed to regular, non-threaded handlers). To clarify its purpose, rename the field to "threaded".
