Subject: [PATCH v2] drm/exynos: Remove dev_err() on platform_get_irq() failure
Date: Tue, 19 May 2020 16:19:04 +0530 [thread overview]
Message-ID: <20200519104904.59246-1-m.shams@samsung.com> (raw)
In-Reply-To: CGME20200519110323epcas5p23b9472d505f5ba58d033fa468cb9969d@epcas5p2.samsung.com
platform_get_irq() will call dev_err() itself on failure,
so there is no need for the driver to also do this.
This is detected by coccinelle.
Also removing unnecessary curly braces around if () statement.
