[PATCH 1/2] usb: gadget: f_fs: resurect usb_functionfs_descs_head structure

2014-06-05 Thread Michal Nazarewicz
Even though usb_functionfs_descs_head structure is now deprecated,
it has been used by some user space tools.  It's removel in commit
[ac8dde1: Add flags to descriptors block] was an oversight leading
to build breakage for such tools.

Bring it back so that old user space tools can still be build
without problems on newer kernel versions.
