Hi all,

Today's linux-next merge of the pinctrl tree got a conflict in:

  drivers/soc/fsl/qe/gpio.c

between commits:

  84582f9ed090 ("soc: fsl: qe: Avoid using gpio_to_desc()")
  66310b5a0fc1 ("soc: fsl: qe: request pins non-exclusively")

from the arm-soc tree and commit:

  c9eb6e546a23 ("soc: fsl: qe: Switch to use fwnode instead of of_node")

from the pinctrl tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

That's correct fix in my opinion. Thank you!

How to avoid conflict and why it's there I have explained here:
