The size of devnode_nums[] bit array is too short to store information for VFL_TYPE_TOUCH. That causes it to override other memory regions. Thankfully, on recent reports, it is overriding video_device[] array, trigging a WARN_ON(). Yet, it just warns about the problem, but let the code excecuting, with generates an OOPS: [ 43.177394] WARNING: CPU: 1 PID: 711 at drivers/media/v4l2-core/v4l2-dev.c:945 __video_register_device+0xc99/0x1090 [videodev] [ 43.177396] Modules linked in: hid_sensor_custom hid_sensor_als hid_sensor_incl_3d hid_sensor_rotation hid_sensor_magn_3d hid_sensor_accel_3d hid_sensor_gyro_3d hid_sensor_trigger industrialio_triggered_buffer kfifo_buf joydev hid_sensor_iio_common hid_rmi(+) rmi_core industrialio videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_common videodev hid_multitouch media hid_sensor_hub binfmt_misc nls_iso8859_1 snd_hda_codec_hdmi arc4 snd_soc_skl snd_soc_skl_ipc snd_hda_ext_core snd_soc_sst_dsp snd_soc_sst_ipc snd_hda_codec_realtek snd_soc_acpi snd_hda_codec_generic snd_soc_core snd_compress ac97_bus snd_pcm_dmaengine snd_hda_intel snd_hda_codec intel_rapl snd_hda_core x86_pkg_temp_thermal snd_hwdep intel_powerclamp coretemp snd_pcm kvm_intel snd_seq_midi snd_seq_midi_event snd_rawmidi crct10dif_pclmul [ 43.177426] crc32_pclmul ghash_clmulni_intel iwlmvm pcbc mac80211 snd_seq aesni_intel iwlwifi aes_x86_64 snd_seq_device crypto_simd glue_helper cryptd snd_timer intel_cstate intel_rapl_perf input_leds serio_raw intel_wmi_thunderbolt snd wmi_bmof cfg80211 soundcore ideapad_laptop sparse_keymap idma64 virt_dma tpm_crb acpi_pad int3400_thermal acpi_thermal_rel intel_pch_thermal processor_thermal_device mac_hid int340x_thermal_zone mei_me intel_soc_dts_iosf mei intel_lpss_pci shpchp intel_lpss sch_fq_codel vfio_pci nfsd vfio_virqfd parport_pc ppdev auth_rpcgss nfs_acl lockd grace lp parport sunrpc ip_tables x_tables autofs4 hid_logitech_hidpp hid_logitech_dj hid_generic usbhid kvmgt vfio_mdev mdev vfio_iommu_type1 vfio kvm irqbypass i915 i2c_algo_bit drm_kms_helper syscopyarea sdhci_pci sysfillrect [ 43.177466] sysimgblt cqhci fb_sys_fops sdhci drm i2c_hid wmi hid video pinctrl_sunrisepoint pinctrl_intel [ 43.177474] CPU: 1 PID: 711 Comm: systemd-udevd Not tainted 4.16.0 #1 [ 43.177475] Hardware name: LENOVO 80UE/VIUU4, BIOS 2UCN10T 10/14/2016 [ 43.177481] RIP: 0010:__video_register_device+0xc99/0x1090 [videodev] [ 43.177482] RSP: 0000:ffffa5c5c231b420 EFLAGS: 00010202 [ 43.177484] RAX: 0000000000000000 RBX: 0000000000000005 RCX: 0000000000000000 [ 43.177485] RDX: ffffffffc0c44cc0 RSI: ffffffffffffffff RDI: ffffffffc0c44cc0 [ 43.177486] RBP: ffffa5c5c231b478 R08: ffffffffc0c96900 R09: ffff8eda1a51f018 [ 43.177487] R10: 0000000000000600 R11: 00000000000003b6 R12: 0000000000000000 [ 43.177488] R13: 0000000000000005 R14: ffffffffc0c96900 R15: ffff8eda1d6d91c0 [ 43.177489] FS: 00007fd2d8ef2480(0000) GS:ffff8eda33480000(0000) knlGS:0000000000000000 [ 43.177490] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 43.177491] CR2: 00007ffe0a6ad01c CR3: 0000000456ae2004 CR4: 00000000003606e0 [ 43.177492] Call Trace: [ 43.177498] ?

NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done.
