removing an ID, the driver will no longer support the

Many of the ingredients in the autosuspend framework are oriented
towards interfaces: The usb_interface structure contains the
pm_usage_cnt field, and the usb_autopm_* routines take an interface
pointer as their argument. But somewhat confusingly, a few of the
pieces (usb_mark_last_busy() and udev->auto_pm) use the usb_device
structure instead. Drivers need to keep this straight; they can call
pieces (i.e., usb_mark_last_busy()) use the usb_device structure
instead. Drivers need to keep this straight; they can call
interface_to_usbdev() to find the device structure for a given
interface.

The Mass Storage Gadget acts as a USB Mass Storage disk drive.
As its storage repository it can use a regular file or a block
device (in much the same way as the "loop" device driver),
specified as a module parameter or sysfs option.
This is heavily based on File-backed Storage Gadget and in most
cases you will want to use FSG instead. This gadget is mostly
here to test the functionality of the Mass Storage Function
which may be used with composite framework.
Say "y" to link the driver statically, or "m" to build
a dynamically linked module called "g_file_storage". If unsure,
consider File-backed Storage Gadget.
