[PATCH] usb: gadget: uvc: Remove extra semicolon from the macro

Posted by Abhishek Tamboli 1 month, 2 weeks ago

Remove the extra semicolon after the
do {} while (0) in UVC_COPY_DESCRIPTOR macro.

Fix the following checkpatch.pl warning

WARNING: do {} while (0) macros should not be semicolon terminated
+#define UVC_COPY_DESCRIPTOR(mem, dst, desc) \
+	do { \
+		memcpy(mem, desc, (desc)->bLength); \
+		*(dst)++ = mem; \
+		mem += (desc)->bLength; \
+	} while (0);
