drivers/usb/gadget/udc/renesas_usb3.c: In function 'renesas_usb3_probe': drivers/usb/gadget/udc/renesas_usb3.c:2638:73: warning: '%d' directive output may be truncated writing between 1 and 11 bytes into a region of size 6 [-Wformat-truncation=] 2638 | snprintf(usb3_ep->ep_name, sizeof(usb3_ep->ep_name), "ep%d", i); ^~~~~~~~~~~~~~~~~~~~~~~~ ^~ ^
Just a record. Since the maximum number of ep is up to 16, such an overflow will not occur actually. Anyway, fixing this compiler warning is good.
Fixes: 8292493c22c8 ("riscv: Kconfig.socs: Add ARCH_RENESAS kconfig option")
Please use the following Fixes tag:
Fixes: 746bfe63bba3 ("usb: gadget: renesas_usb3: add support for Renesas USB3.0 peripheral controller")
Okay
Best regards, Yoshihiro Shimoda
