Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Signed-off-by:

This patch fixes a sparse warning about using an incorrect type in argument 2 of ocelot_write_rix(), as an u32 was expected but a __be32 was given.

When using s/w buffer management, buffers are allocated and DMA mapped. When doing so on an arm64 platform, an offset correction is applied on the DMA address, before storing it in an Rx descriptor. The issue is this DMA address is then used later in the Rx path without removing the offset correction. Thus the DMA address is wrong, which can led to various issues. This patch fixes this by removing the offset correction from the DMA address retrieved from the Rx descriptor before using it in the Rx path.

Recent patch updated e1000 docs to rst format. Docs build (`make htmldocs`) is currently failing due to this file with error: (SEVERE/4) Unexpected section title. This is because a section of the file is indented 2 spaces. Build error can be cleared by aligning the text with column 0. While we are changing these lines we can make sure line length does not exceed 72, that newlines following headings are uniform, and that full stops are followed by two spaces. Align text with column 0, limit line length to 72, ensure two spaces follow all full stops, ensure uniform use of newlines after heading.

After recieving MLD querys, we update idev->mc_maxdelay with max_delay from query header. This make the later unsolicited reports have the same interval with mc_maxdelay, which means we may send unsolicited reports with long interval time instead of default configured interval time. Also as we will not call ipv6_mc_reset() after device up. This issue will be there even after leave the group and join other groups.

The dst_cid and src_cid are 64 bits, therefore 64 bit accessors should be used, and in fact in virtio_transport_common.c only 64 bit accessors are used. Using 32 bit accessors for 64 bit values breaks big endian systems. This patch fixes a wrong use of le32_to_cpu in virtio_transport_send_pkt.

Commit 296d4856 ("ipvlan: inherit MTU from master device") adjusted the mtu from the master device when creating a ipvlan device, but it would also override the mtu value set in rtnl_create_link. It causes IFLA_MTU param not to take effect. So this patch is to not adjust the mtu if IFLA_MTU param is set when creating a ipvlan device.

When injecting frames in the Ocelot switch driver an injection header (IFH) should be used to configure various parameters related to a given frame, such as the port onto which the frame should be departed or its vlan id. Other parameters in the switch configuration can led to an injected frame being sent without an IFH but this led to various issues as the per-frame parameters are then not used. This is especially true when using multiple ports for injection. The IFH was injected with the wrong endianness which led to the switch not taking it into account as the IFH_INJ_BYPASS bit was then unset. (The bit tells the switch to use the IFH over its internal configuration). This patch fixes it. In addition to the endianness fix, the IFH is also fixed. As it was (unwillingly) unused, some of its fields were not configured the right way. Fixes: a556c76a ("net: mscc: Add initial Ocelot switch support") Signed-off-by:

In function strp_data_ready(), it is useless to call queue_work if the state of strparser is already paused. The state checking should be done before calling queue_work. The change reduces the context switches and improves the ktls-rx throughput by approx 20% (measured on cortex-a53 based platform). Signed-off-by:

The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains a typo which defines an incorrect logical maximum Y value. This causes a small portion of the bottom of the tablet to become unusable (both because the area is below the "bottom" of the tablet and because 'wacom_wac_event' ignores out-of-range values). It also results in a skewed aspect ratio. To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites the data with the correct value. Signed-off-by:

Current ISH driver only registers suspend/resume PM callbacks which don't support hibernation (suspend to disk). Basically after hiberation, the ISH can't resume properly and user may not see sensor events (for example: screen rotation may not work). User will not see a crash or panic or anything except the following message in log: hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device So this patch adds support for S4/hiberbation to ISH by using the SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend and resume functions will now be used for both suspend to RAM and hibernation. If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend and resume related functions won't be used, so mark them as __maybe_unused to clarify that this is the intended behavior, and remove #ifdefs for power management.

When creating the low-level hidraw device, the reference to steam_device was stored using hid_set_drvdata(). But this value is not guaranteed to be kept when set before calling probe. If this pointer is reset, it crashes when opening the emulated hidraw device. It looks like hid_set_drvdata() is for users "avobe" this hid_device, while hid_device.driver_data it for users "below" this one. In this case, we are creating a virtual hidraw device, so we must use hid_device.driver_data. Signed-off-by:

The rewrite of the cmdline fetching missed the fact that we used to also return the final terminating NUL character of the last argument. I hadn't noticed, and none of the tools I tested cared, but something obviously must care, because Michal Kubecek noticed the change in behavior. Tweak the "find the end" logic to actually include the NUL character, and once past the eend of argv, always start the strnlen() at the expected (original) argument end. This whole "allow people to rewrite their arguments in place" is a nasty hack and requires that odd slop handling at the end of the argv array, but it's our traditional model, so we continue to support it.

The Stratix10 platform has an additional reset line, OCP(Open Core Protocol), that also needs to get deasserted for the stmmac ethernet controller to work. Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build dwmac-socfpga. Also, remove the redundant check for the reset controller pointer. The reset driver already checks for the pointer and returns 0 if the pointer is NULL. Signed-off-by:
