Subject: [PATCH] gpio: brcmstb: correct the configuration of level interrupts
Git-commit: 633007a36e51c5dd85a20e9ebd17de12566cf2c2
Patch-mainline: v4.15-rc1
References: bsc#1051510

This commit corrects a bug when configuring the GPIO hardware for
IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH interrupt types. The
hardware is now correctly configured to support those types.

Fixes: 19a7b6940b78 ("gpio: brcmstb: Add interrupt and wakeup source support")
