s_priv was set but never used in keyspan_open() and keyspan_close(), remove it. This also makes the serial variable in keyspan_open() unused since it's only use was to set s_priv, so it is also removed.

Ensure that intfdata always is NULL if no driver is bound: 1) drvdata is for a driver to store a pointer to driver specific data 2) If no driver is bound, there is no driver specific data associated with the device 3) Thus logically drvdata should be NULL if no driver is bound. We already set intfdata to NULL when a driver is unbound, to ensure that intfdata will be NULL even if the drivers disconnect method does not properly clear it. This ensures that intfdata will also be NULL after a failed probe, even if the driver's probe method left a (likely dangling) pointer in there.

Some composite USB devices provide multiple interfaces with different functions, all using "vendor-specific" for class/subclass/protocol. Another OS use interface numbers to match the driver and interface. It seems these devices are designed with that in mind - using static interface numbers for the different functions. This adds support for matching against the bInterfaceNumber, allowing such devices to be supported without having to resort to testing against interface number whitelists and/or blacklists in the probe.

This class was not named properly years ago, and it turns out that tools like udev can't properly see the devices in this class after booting due to the fact that there is a bus with the same name in the system. Changing this to "usbmisc" fixes this problem, and it solves the problem for the future when we want to unify classes and busses.

The usb-serial-generic driver uses different device IDs for its USB matching and its serial matching. This can lead to problems: The driver can end up getting bound to a USB interface without being allowed to bind to the corresponding serial port. This patch (as1557) fixes the problem by using the same device ID table (the one that can be altered by the "vendor=" and "product=" module parameters) for both purposes. The unused table is removed. Now the driver will bind only to the intended devices.

We need to make sure that the USB serial driver we find matches the USB driver whose probe we are currently executing.

This patch (as1558) fixes a problem affecting several ASUS computers: The machine crashes or corrupts memory when going into suspend if the ehci-hcd driver is bound to any controllers. Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. A similar patch has already been applied as commit 151b6128 (USB: EHCI: fix crash during suspend on ASUS computers). The patch supersedes that one and reverts it. There are two differences: The old patch added the flag at the USB level; this patch adds it at the PCI level. The old patch applied to all chipsets with the same vendor, subsystem vendor, and product IDs; this patch makes an exception for a known-good system (based on DMI information).

This reverts commit 9e612a00. It incorrectly finds VGA connectors where none are attached, apparently not noticing that nothing replied to the EDID queries, and happily using the default EDID modes that have nothing to do with actual hardware. That in turn then causes X to fall down to the lowest common denominator, which is usually the default 1024x768 mode that is in the default EDID and pretty much anything supports). I'd suggest that if not relying on the HDP pin, the code should at least check whether it gets valid EDID data back, rather than just assume there's something on the VGA connector.

We do not need to have it in write mode - read mode is enough, and we do not need to hole it over the entire loop. So this patch turns changes the locking: takes 'work_sem' in read mode and pushes it down to the loop. Signed-off-by: NArtem Bityutskiy <artem.bityutskiy@linux.intel.com>

Limit the max number of WQEs per QP reported when querying the device, so that ib_create_qp() will not fail for a QP size that the device claimed to support due to additional headroom WQEs being allocated. 2. Limit qp resources accepted for ib_create_qp() to the limits reported in ib_query_device(). In kernel space, make sure that the limits returned to the caller following qp creation also lie within the reported device limits. For userspace, report as before, and do adjustment in libmlx4 (so as not to break ABI).

Commit 096335b3 ("mlx4_core: Allow dynamic MTU configuration for IB ports") modifies the port VL setting. This exposes a bug in mlx4_common_set_port(), where the VL cap value passed in (inside the command mailbox) is incorrectly zeroed-out: mlx4_SET_PORT modifies the VL_cap field (byte 3 of the mailbox). Since the SET_PORT command is paravirtualized on the master as well as on the slaves, mlx4_SET_PORT_wrapper() is invoked on the master. This calls mlx4_common_set_port() where mailbox byte 3 gets overwritten by code which should only set a single bit in that byte (for the reset qkey counter flag) -- but instead overwrites the entire byte. The result is that when running in SR-IOV mode, the VL_cap will be set to zero -- fix this.

Or at least plug another gapping hole. Apparrently hw desingers only moved the bit field, but did not bother ot re-enumerate the planes when adding support for a 3rd pipe. Discovered by i-g-t/flip_test. This may or may not fix the reference bugzilla, because that one smells like we have still larger fish to fry. v2: Fixup the impossible case to catch programming errors, noticed by Chris Wilson.

Locking mutex in different orders just screams for deadlocks, and some testing showed that it is actually quite easy to trigger them.

Many TVs and A/V receivers don't work with this bit set. Problem was confirmed using: Onkyo TX-SR605, Sony BRAVIA KDL-52X3500, Sony BRAVIA KDL-40S40xx. In theory this bit shouldn't affect audio engine when feeding it with data, however it seems it does. Driver fglrx doesn't set that bit in any of the above cases. This fixes a regression introduced by 3.5-rc1. Signed-off-by: NRafał Miłecki <zajec5@gmail.com> Reviewed-by: NAlex Deucher <alexander.deucher@amd.com> Signed-off-by: NDave Airlie <airlied@redhat.com>
