thanks for this explanation..

my intention was trying to keep struct members aligned
if tabs is a no-go, would using multi blank spaces to align be acceptable?

something like:

struct spacemit_gpio_bank {
	struct gpio_chip       gc;
	struct spacemit_gpio   *sg;
	void   __iomem         *base;
       ...
}
