Subject: [PATCH v6 1/2] usb: rename phy to usb_phy in HCD
From: Antoine Tenart <antoine.tenart@...e-electrons.com>
The USB PHY member of the HCD structure is renamed to 'usb_phy' and
modifications are done in all drivers accessing it.
This is in preparation to adding the generic PHY support.
Signed-off-by: Antoine Tenart <antoine.tenart@...e-electrons.com>
[Sergei: added missing 'drivers/usb/misc/lvstest.c' file, resolved rejects,
updated changelog.]
