Hello.

gadget.h uses structures defined in device.h, it must include it. In
most cases, gadget.h is preceded by linux/platform_device.h, but if
you are grouping headers sanely, device.h may not be pulled in until
*after* gadget (e.g. mach/msm_device.h), thus gadget.h should not
rely on something else #including device.h

Sigh, I've already submitted a more complete patch, adding 6 #include's but it seems that prevailing opinion in this list is to leave things as they are in the header, and deal with the fallout wherever it's used.

Besides, this is not against the recent kernel -- there should be #include <linux/slab.h> here.
