[PATCH 6.19 591/781] mfd: sec: Fix IRQ domain names duplication

From: André Draszik <andre.draszik@linaro.org>

[ Upstream commit b60c2dba6d3c3ad72a7c30bbd8eda07d8a49bc7f ]

For the S2MPG10 IRQ and chained IRQ, regmap IRQ will try to create a
folder with the same name which is impossible and fails with:

debugfs: ':firmware:power-management:pmic' already exists in 'domains'

Add domain_suffix to the chained IRQ chip driver to fix it.
