Thanks for the hint! I will drop this hunk. Originally, it made sure
that USB_DEV_NEED_CLK_EN is disabled but due to another change:
usb_hcd_nxp_probe() {
...
__raw_writel(USB_SLAVE_HCLK_EN | PAD_CONTROL_LAST_DRIVEN, USB_CTRL);
this bit is already cleared anyway.
(Would have been uncritical for v3.4 anyway, relating only to the other
changes introduced in my 3.5 patches.)
