Subject: [PATCH 0/2] gpiolib: linehandle_ioctl() tweaks
Date: Mon, 16 Jul 2018 10:34:22 +0200	[thread overview]
Message-ID: <20180716083424.11157-1-brgl@bgdev.pl> (raw)

I noticed that - unlike sysfs - it's possible to set values of input
lines from user space using the character device. There's actually
even a TODO in the linehandle_ioctl() code.

This is not correct so the first patches fixes that and the second
removes a TODO that's not really needed.

Bartosz Golaszewski (2):
  gpiolib: don't allow userspace to set values of input lines
  gpiolib: remove an unneccessary TODO
