Subject: [PATCH] soc: fsl: qe: convert set_multiple() to returning an integer

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

The conversion to using the new GPIO line setter callbacks missed the
set_multiple() in this file. Convert it to using the new callback.

Fixes: 52ccf19527fd ("soc: fsl: qe: use new GPIO line value setter callbacks")
Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
---
This is a follow-up to commit 52ccf19527fd ("soc: fsl: qe: use new GPIO
line value setter callbacks") in which I did not convert the second GPIO
callback. Could you please apply it on top of Christophe's
pull-request[1] and queue it for v6.17?
