2018-07-04Input: eeti - drop module parameters, parse DT propertiesDaniel Mack1-17/+5
The only user of this driver in mainline does not make use of the module parameters, so let's remove them. All properties for this driver should be set through DT or pdata. Use touchscreen_parse_properties() to automatically set some of the common touchscreen properties and derive the axis inversion through that. And finally, use touchscreen_report_pos() to handle the DT properties automatically instead of doing the inversion ourselves.

2018-06-12Input: xen-kbdfront - allow better run-time configurationOleksandr Andrushchenko1-71/+106
It is now only possible to control if multi-touch virtual device is created or not (via the corresponding XenStore entries), but keyboard and pointer devices are always created. In some cases this is not desirable. For example, if virtual keyboard device is exposed to Android then the latter won't automatically show on-screen keyboard as it expects that a physical keyboard device can be used for typing. Utilize keyboard and pointer device XenStore feature fields to configure which virtual devices are created: - set "feature-disable-keyboard" to 1 if no keyboard device needs to be created - set "feature-disable-pointer" to 1 if no pointer device needs to be created Keep old behavior by default.

2018-05-31ixgbe: fix parsing of TC actions for HW offloadOndřej Hlavatý1-5/+4
The previous code was optimistic, accepting the offload of whole action chain when there was a single known action (drop/redirect). This results in offloading a rule which should not be offloaded, because its behavior cannot be reproduced in the hardware. For example: $ tc filter add dev eno1 parent ffff: protocol ip \ u32 ht 800: order 1 match tcp src 42 FFFF \ action mirred egress mirror dev enp1s16 pipe \ drop The controller is unable to mirror the packet to a VF, but still offloads the rule by dropping the packet. Change the approach of the function to a pessimistic one, rejecting the chain when an unknown action is found. This is better suited for future extensions. Note that both recognized actions always return TC_ACT_SHOT, therefore it is safe to ignore actions behind them.

2018-05-31platform/x86: asus-wmi: Fix NULL pointer dereferenceJoão Paulo Rechi Vita1-10/+13
Do not perform the rfkill cleanup routine when (asus->driver->wlan_ctrl_by_user && ashs_present()) is true, since nothing is registered with the rfkill subsystem in that case. Doing so leads to the following kernel NULL pointer dereference: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffff816c7348>] __mutex_lock_slowpath+0x98/0x120 PGD 1a3aa8067 PUD 1a3b3d067 PMD 0 Oops: 0002 [#1] PREEMPT SMP Modules linked in: bnep ccm binfmt_misc uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core hid_a4tech videodev x86_pkg_temp_thermal intel_powerclamp coretemp ath3k btusb btrtl btintel bluetooth kvm_intel snd_hda_codec_hdmi kvm snd_hda_codec_realtek snd_hda_codec_generic irqbypass crc32c_intel arc4 i915 snd_hda_intel snd_hda_codec ath9k ath9k_common ath9k_hw ath i2c_algo_bit snd_hwdep mac80211 ghash_clmulni_intel snd_hda_core snd_pcm snd_timer cfg80211 ehci_pci xhci_pci drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops drm xhci_hcd ehci_hcd asus_nb_wmi(-) asus_wmi sparse_keymap r8169 rfkill mxm_wmi serio_raw snd mii mei_me lpc_ich i2c_i801 video soundcore mei i2c_smbus wmi i2c_core mfd_core CPU: 3 PID: 3275 Comm: modprobe Not tainted 4.9.34-gentoo #34 Hardware name: ASUSTeK COMPUTER INC.

2018-05-30Input: ti_am335x_tsc - prevent system suspend when TSC is in useGrygorii Strashko1-0/+3
Prevent system suspend while user has finger on touch screen, because TSC is wakeup source and suspending device while in use will result in failure to disable the module. This patch uses pm_stay_awake() and pm_relax() APIs to prevent and resume system suspend as required.

2018-05-30Input: ti_am335x_tsc - ack pending IRQs at probe and before suspendGrygorii Strashko1-0/+4
It is seen that just enabling the TSC module triggers a HW_PEN IRQ without any interaction with touchscreen by user. This results in first suspend/resume sequence to fail as system immediately wakes up from suspend as soon as HW_PEN IRQ is enabled in suspend handler due to the pending IRQ. Therefore clear all IRQs at probe and also in suspend callback for sanity.

2018-05-30Input: cros_ec_keyb - mark cros_ec_keyb driver as wake enabled device.Ravi Chandra Sadineni2-24/+28
Mark cros_ec_keyb has wake enabled by default. If we see a MKBP event related to keyboard, call pm_wakeup_event() to make sure wakeup triggers are accounted to keyb during suspend resume path.
