Subject: Nagging free/reclaim gpio's
Date: Mon, 30 Aug 2010 14:25:39 -0400 [thread overview]
Message-ID: <4C7BF7A3.3000900@balister.org> (raw)
I've got a module that claims gpio's when it is loaded and frees them
when it is unloaded. It looks like something goes wrong when I free them:
gpio_unexport: gpio144 status -22
gpio_unexport: gpio146 status -22
gpio_unexport: gpio14 status -22
gpio_unexport: gpio21 status -22
gpio_unexport: gpio22 status -22
gpio_unexport: gpio23 status -22
Then when I try to reclaim them I get this:
gpio_request: gpio-175 (sysfs) status -16
export_store: status -16
gpio_request: gpio-175 (sysfs) status -16
export_store: status -16
gpio_request: gpio-114 (sysfs) status -16
export_store: status -16
gpio_request: gpio-114 (sysfs) status -16
export_store: status -16
gpio_request: gpio-173 (sysfs) status -16
export_store: status -16
gpio_request: gpio-173 (sysfs) status -16
export_store: status -16
This has to be silly, but I can't find the problem. Everything works
fine, I just would like the messages to go away :)
