      HID: wacom: Correct logical maximum Y for 2nd-gen Intuos Pro large · d471b6b2
      Jason Gerecke authored
      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.

      HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation · ebeaa367
      Even Xu authored
      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.

      HID: steam: use hid_device.driver_data instead of hid_set_drvdata() · 4bff980f
      Rodrigo Rivas Costa authored
      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.

      proc: fix missing final NUL in get_mm_cmdline() rewrite · f5b65348
      Linus Torvalds authored
      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.

      ip: limit use of gso_size to udp · 9887cba1
      Willem de Bruijn authored
      The ipcm(6)_cookie field gso_size is set only in the udp path. The ip
      layer copies this to cork only if sk_type is SOCK_DGRAM. This check
      proved too permissive. Ping and l2tp sockets have the same type.
      
      Limit to sockets of type SOCK_DGRAM and protocol IPPROTO_UDP to
      exclude ping sockets.

      net: stmmac: socfpga: add additional ocp reset line for Stratix10 · bc8a2d9b
      Dinh Nguyen authored
      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.

      net: sungem: fix rx checksum support · 12b03558
      Eric Dumazet authored
      After commit 88078d98 ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE
      are friends"), sungem owners reported the infamous "eth0: hw csum failure"
      message.
      
      CHECKSUM_COMPLETE has in fact never worked for this driver, but this
      was masked by the fact that upper stacks had to strip the FCS, and
      therefore skb->ip_summed was set back to CHECKSUM_NONE before
      my recent change.
      
      Driver configures a number of bytes to skip when the chip computes
      the checksum, and for some reason only half of the Ethernet header
      was skipped.
      
      Then a second problem is that we should strip the FCS by default,
      unless the driver is updated to eventually support NETIF_F_RXFCS in
      the future.
      
      Finally, a driver should check if NETIF_F_RXCSUM feature is enabled
      or not, so that the admin can turn off rx checksum if wanted.
      
      Many thanks to Andreas Schwab and Mathieu Malaterre for their
      help in debugging this issue.
