From f1a0a9948f71703f1920bb63072736e76bd6ccfa Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 30 Jun 2020 13:45:21 +0200 Subject: udc: lpc32xx: mark local function static The kernel test robot reports two functions that should be marked static: >> drivers/usb/gadget/udc/lpc32xx_udc.c:1928:6: warning: no previous prototype for 'udc_send_in_zlp' [-Wmissing-prototypes] 1928 | void udc_send_in_zlp(struct lpc32xx_udc *udc, struct lpc32xx_ep *ep) >> drivers/usb/gadget/udc/lpc32xx_udc.c:1942:6: warning: no previous prototype for 'udc_handle_eps' [-Wmissing-prototypes] 1942 | void udc_handle_eps(struct lpc32xx_udc *udc, struct lpc32xx_ep *ep) This showed up after my commit 792e559e94bc ("udc: lpc32xx: fix 64-bit compiler warning") made it possible to build the driver on x86-64. Fix the warning as suggested.
