[PATCH 5/8] drm/exynos/fimc: simplify irq masking function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
