From cef1717b7ff9ad7de747aedb5d222936913570fd Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 4 May 2015 17:10:48 +0200 Subject: gpio: sysfs: move irq trigger flags to class-device data Move irq trigger flags, which as sysfs-interface specific, to the class device data. This avoids accessing the gpio-descriptor flags field using non-atomic operations without any locking, and allows for a more clear separation of the sysfs interface from gpiolib core.
