[PATCH 4.19 05/46] USB: xhci: fix broken_suspend placement in struct xchi_hcd

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicolas Saenz Julienne <nsaenzjulienne@xxxxxxx>

commit 2419f30a4a4fcaa5f35111563b4c61f1b2b26841 upstream.

As commented in the struct's definition there shouldn't be anything
underneath its 'priv[0]' member as it would break some macros.

The patch converts the broken_suspend into a bit-field and relocates it
next to to the rest of bit-fields.
