Subject: [PATCH v7 07/14] gpio: thunderx: Use the default parent apis for {request,release}_resources
Date: Sat, 20 Apr 2019 15:39:43 +0530 [thread overview]
Message-ID: <20190420100950.7997-8-lokeshvutla@ti.com> (raw)
In-Reply-To: <20190420100950.7997-1-lokeshvutla@ti.com>
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.
