Use #if IS_ENABLED() instead of #ifdef for configurations as vendor module
guidelines.
Use #if IS_ENABLED(CONFIG_XXX) instead of #ifdef CONFIG_XXX to ensure that
the code inside the #if block continues to compile if the config changes
to a tristate config in the future.
The differences are as follows:
1.#if IS_ENABLED(CONFIG_XXX) evaluates to true when CONFIG_XXX is set to
module (=m) or built-in (=y).
2.#ifdef CONFIG_XXX evaluates to true when CONFIG_XXX is set to
built-in(=y) , but doesn't when CONFIG_XXX is set to module(=m).
Use this only when you're certain you want to do the same thing
when the config is set to module or is disabled.
