Build failure in drivers/net/wwan/mhi_wwan_mbim.c:
add missing parameter (0, assuming we don't want buffer pre-alloc).

Syzbot reported uninit value pegasus_probe(). The problem was in missing
error handling.
get_interrupt_interval() internally calls read_eprom_word() which can
fail in some cases. For example: failed to receive usb control message.
These cases should be handled to prevent uninit value bug, since
read_eprom_word() will not initialize passed stack variable in case of
internal failure.

Currently phy_device state could be left in inconsistent state shown
by following alert message[1]. This is because phy_read_status could
be called concurrently from lan78xx_delayedwork, phy_state_machine and

Most users of ndo_do_ioctl are ethernet drivers that implement
the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware
timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP.
Separate these from the few drivers that use ndo_do_ioctl to
implement SIOCBOND, SIOCBR and SIOCWANDEV commands.
This is a purely cosmetic change intended to help readers find
their way through the implementation.

asix_get_phyid() is used for two reasons here. To print debug message
with the PHY ID and to wait until the PHY is powered up.
After migrating to the phylib, we can read PHYID from sysfs. If polling
for the PHY is really needed, then we will need to handle it in the
phylib as well.
This change was tested with:
- ax88772a + internal PHY
- ax88772b + external PHY

After probe/bind sequence is the PHY in active state, even if interface

board, the ASIX PHY will be able to negotiate the link but fail to

When the QMI_WWAN_FLAG_PASS_THROUGH is set, netif_rx() is called from
qmi_wwan_rx_fixup(). When the call to netif_rx() is successful (which is
most of the time), usbnet_skb_return() is called (from rx_process()).
usbnet_skb_return() will then call netif_rx() a second time for the same
skb.
Simplify the code and avoid the redundant netif_rx() call by changing
qmi_wwan_rx_fixup() to always return 1 when QMI_WWAN_FLAG_PASS_THROUGH
is set. We then leave it up to the existing infrastructure to call
netif_rx().

This is meant to make the host side cdc_ncm interface consistently
named just like the older CDC protocols: cdc_ether & cdc_ecm
(and even rndis_host), which all use 'FLAG_ETHER | FLAG_POINTTOPOINT'.
include/linux/usb/usbnet.h:
#define FLAG_ETHER 0x0020 /* maybe use "eth%d" names */
#define FLAG_WLAN 0x0080 /* use "wlan%d" names */
#define FLAG_WWAN 0x0400 /* use "wwan%d" names */
#define FLAG_POINTTOPOINT 0x1000 /* possibly use "usb%d" names */
drivers/net/usb/usbnet.c @ line 1711:
strcpy (net->name, "usb%d");
...
// heuristic: "usb%d" for links we know are two-host,
// else "eth%d" when there's reasonable doubt. userspace
// can rename the link if it knows better.
if ((dev->driver_info->flags & FLAG_ETHER) != 0 &&
((dev->driver_info->flags & FLAG_POINTTOPOINT) == 0 ||
(net->dev_addr [0] & 0x02) == 0))
strcpy (net->name, "eth%d");
/* WLAN devices should always be named "wlan%d" */
if ((dev->driver_info->flags & FLAG_WLAN) != 0)
strcpy(net->name, "wlan%d");
/* WWAN devices should always be named "wwan%d" */
if ((dev->driver_info->flags & FLAG_WWAN) != 0)
strcpy(net->name, "wwan%d");
So by using ETHER | POINTTOPOINT the interface naming is
either usb%d or eth%d based on the global uniqueness of the
mac address of the device.
Without this 2.5gbps ethernet dongles which all seem to use the cdc_ncm
driver end up being called usb%d instead of eth%d even though they're
definitely not two-host. (All 1gbps & 5gbps ethernet usb dongles I've
tested don't hit this problem due to use of different drivers, primarily
r8152 and aqc111)
Fixes tag is based purely on git blame, and is really just here to make
sure this hits LTS branches newer than v4.5.

The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the tiocmset and rfkill requests which erroneously used
usb_rcvctrlpipe().

Verify some fields of the USB descriptor to make sure the driver
could be used by the device.
Besides, remove the check of endpoint number in rtl8152_probe().
usb_find_common_endpoints() includes it.

Use DEVICE_ATTR_RW helper instead of plain DEVICE_ATTR,
which makes the code a bit shorter and easier to read.

Commit 31db0dbd7244 ("net: hso: check for allocation failure in
hso_create_bulk_serial_device()") recently started returning an error
when the driver fails to allocate resources for the interrupt endpoint
and tiocmget functionality.
For consistency let's bail out from probe also if the URB allocation
fails.

Override .get_ts_info to also advertise this capability
