drivers/usb/gadget/r8a66597-udc.h:139: warning: âdataâ may be used uninitialized in this function

[Daniel Mack]

Hi,

I stumbled over the r8a66597 UDC gadget driver as the the compiler
complained about the static inline function r8a66597_read():

drivers/usb/gadget/r8a66597-udc.c: In function âirq_packet_readâ:
drivers/usb/gadget/r8a66597-udc.h:139: warning: âdataâ may be used uninitialized in this function
drivers/usb/gadget/r8a66597-udc.h:139: note: âdataâ was declared here

I know nothing about the code, but this function indeed looks bogus. Can
anyone have a look at this? Also, I wonder whether this function is
actually too big for a static inline.

Thanks,
Daniel
