[PATCH v3 1/3] staging: greybus: Inline gpio_chip_to_gb_gpio_controller()

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


Convert 'gpio_chip_to_gb_gpio_controller' from a macro to a static
inline function, to make the relevant types apparent in the
definition and to benefit from the type checking performed by
the compiler at call sites.
