Modern gcc versions warn about returning a ternary operator with an 'int'
type in a function returning type 'bool':
drivers/gpu/drm/exynos/exynos_drm_scaler.c: In function 'scaler_task_done':
drivers/gpu/drm/exynos/exynos_drm_scaler.c:402:47: error: ?: using integer constants in boolean context [-Werror=int-in-bool-context]
return val & SCALER_INT_STATUS_FRAME_END ? 0 : -EINVAL;
>From context, it becomes clear that this should have been 'int',
so I'm fixing it, along with parenthesizing the expression to make
it clearer what is meant here (I got confused at first, after seeing
the warning).
Fixes: 01fb9185dc18 ("drm/exynos: Add driver for Exynos Scaler module")
