Using flexible array is more straight forward. It - saves 1 pointer in the 'gsc_hwmon_platform_data' structure - saves an indirection when using this array - saves some LoC and avoids some always spurious pointer arithmetic Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/61a23e1d642397cfcecc4ac3bb0ab485d257987d.1668936855.git.christophe.jaillet@wanadoo.fr Signed-off-by: Guenter Roeck <linux@roeck-us.net>
