Subject: [PATCH] pinctrl: baytrail: Use platform_get_irq_optional() explicitly
Git-commit: f86a1bb536064a431c36d4333f4a2295b2419477
Patch-mainline: v5.8-rc1
References: jsc#SLE-12730

There is no need to repeat functionality of platform_get_irq_optional()
in the driver. Replace it with explicit call to the helper.
