-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Move the conflicting declaration to the end of the structure. Notice that `struct uvc_input_header_descriptor` is a flexible structure --a structure that contains a flexible-array member. With this, fix three of the following warnings: drivers/usb/gadget/function/uvc_configfs.h:77:57: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.
