The code was fixed in
commit 53642399aa71 ("usb: gadget: f_fs: Fix wrong check on reserved1 wof OS_DESC_EXT_COMPAT")
but the in-header documentation kept referencing 0 as the expected value.
Reference 1 instead as per original commit message.

The specification says that the Reserved1 field in OS_DESC_EXT_COMPAT
must have the value "1", but when this feature was first implemented we
rejected any non-zero values.
This was adjusted to accept all non-zero values (while now rejecting
zero) in commit 53642399aa71 ("usb: gadget: f_fs: Fix wrong check on
reserved1 of OS_DESC_EXT_COMPAT"), but that breaks any userspace
programs that worked previously by returning EINVAL when Reserved1 == 0
which was previously the only value that succeeded!
If we just set the field to "1" ourselves, both old and new userspace
programs continue to work correctly and, as a bonus, old programs are
now compliant with the specification without having to fix anything
themselves.

This reverts commit ac670a3a650b899fc020b81f63e810d06015b865.
This introduce bug we already fixed in

Current __ffs_data_do_os_desc() of f_fs.c will check reserved1 field
of OS_DESC_EXT_COMPAT and return -EINVAL if it's 1.
But MS OS 1.0 Descriptors
http://msdn.microsoft.com/en-us/library/windows/hardware/gg463179.aspx
