From 0d04d0c146786da42c6e68c7d2f09c956c5b5bd3 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Tue, 30 Apr 2019 15:42:23 +0530 Subject: [PATCH] gpio: thunderx: Use the default parent apis for {request,release}_resources thunderx_gpio_irq_{request,release}_resources apis are trying to {request,release} resources on parent interrupt. There are default apis doing the same. Use the default parent apis instead of writing the same code snippet.
