Subject: [PATCH 5/8] drm/exynos/fimc: simplify irq masking function
Date: Mon, 19 May 2014 12:54:07 +0200	[thread overview]
Message-ID: <1400496850-23860-6-git-send-email-a.hajda@samsung.com> (raw)
In-Reply-To: <1400496850-23860-1-git-send-email-a.hajda@samsung.com>

The name fimc_handle_irq suggests it is irq handler, but the function
is for irq mask configuration. The patch renames the function to
fimc_mask_irq and removes unused arguments.
