[PATCH v2] Staging: nvec: Convert to_nvec_led from a macro to an inline function

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


Convert to_nvec_led 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.

v2: Change patch subject and description, noted by 
Julia Lawall <julia.lawall@xxxxxxxx>
