This doesn't belong to your patch, but the above 2 lines could be written as:
struct exynos_dp_device *dp = dev_get_drvdata(&pdev->dev);
Same in functions exynos_dp_suspend() and exynos_dp_resume().
No, above 2 lines cannot be reduced to 1 line, as you mentioned.
This is because it makes build error.
Sorry, my bad. It looks fine in case of exynos_dp_remove().
But at exynos_dp_suspend/resume() there is something like:
static int exynos_dp_suspend(struct device *dev)
{
struct platform_device *pdev = to_platform_device(dev);
struct exynos_dp_platdata *pdata = pdev->dev.platform_data;
struct exynos_dp_device *dp = platform_get_drvdata(pdev);
You need only pdata and dp there. I think that simpler form would
do as well:
struct exynos_dp_device *dp = dev_get_drvdata(dev);
struct exynos_dp_platdata *pdata = dev->platform_data;
Sorry, this is just a nitpicking.
BTW, shouldn't CONFIG_EXYNOS_VIDEO depend on ARCH_EXYNOS ?
