cdc-acm: delete obsolete debug messages · ab57f861

由 Oliver Neukum 提交于 9月 07, 2016

Some debug messages merely provide a function trace without
additional debug data. They predate ftrace and can be replaced
by it. Drop them without replacement.

The ULPI bus is not only for host, but for device mode too, so move

usb: gadget: use IS_ENABLED() instead of checking for built-in or module · 3112fdde

由 Javier Martinez Canillas 提交于 8月 18, 2016

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.

usb: usbip: vudc: fix left shift overflow · 238b7bd9

由 Nicolas Iooss 提交于 8月 23, 2016

In v_recv_cmd_submit(), urb_p->urb->pipe has the type unsigned int
(which is 32-bit long on x86_64) but 11<<30 results in a 34-bit integer.
Therefore the 2 leading bits are truncated and

    urb_p->urb->pipe &= ~(11 << 30);

has the same meaning as

    urb_p->urb->pipe &= ~(3 << 30);

This second statement seems to be how the code was intended to be
written, as PIPE_ constants have values between 0 and 3.

The overflow has been detected with a clang warning:

    drivers/usb/usbip/vudc_rx.c:145:27: warning: signed shift result
    (0x2C0000000) requires 35 bits to represent, but 'int' only has 32
    bits [-Wshift-overflow]
            urb_p->urb->pipe &= ~(11 << 30);
                                  ~~ ^  ~~

usb: ohci-sa1111: remove machine_has_neponset() · 6ebb8f0f

由 Russell King 提交于 8月 26, 2016

The neponset is a daughter board for the Assabet platform, which has a
SA1111 chip on it.  If we're initialising the SA1111 OHCI, and we're
part of a neponset, the host platform must be an Assabet.

This allows us to eliminate machine_has_neponset() from this driver,
replacing it instead with machine_is_assabet(), and killing the
mach/assabet.h include.

usb: ohci-at91: Forcibly suspend ports while USB suspend · 2e2aa1bc

由 Wenyou Yang 提交于 8月 23, 2016

The usb controller does not manage correctly the suspend mode for
the ehci. In echi mode, there is no way to suspend without any
device connected to it. This is why this specific control is added
to fix this issue. Since the suspend mode works in ohci mode, this
specific control works by suspend the usb controller in ohci mode.

This specific control is by setting the SUSPEND_A/B/C fields of
SFR_OHCIICR(OHCI Interrupt Configuration Register) in the SFR
while the OHCI USB suspend.

This set operation must be done before the USB clock disabled,
clear operation after the USB clock enabled.
