Subject: linux-next: build failure after merge of the pinctrl tree

Hi all,

After merging the pinctrl tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/pinctrl/tegra/pinctrl-tegra.c: In function 'tegra_pinctrl_get_group':
drivers/pinctrl/tegra/pinctrl-tegra.c:293:12: warning: return discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]

Caused by commit

  a42c7d95d29e ("pinctrl: tegra: Use correct offset for pin group")

I have used the pinctrl tree from next-20211025 for today.

The tegra_pinctrl_get_group() should return const and not cast the pointers. Please make another patch to fix it properly.
