      staging: android: ion: Return an ERR_PTR in ion_map_kernel · 58fcaeb3
      Laura Abbott authored 
      commit 0a2bc003 upstream.

The expected return value from ion_map_kernel is an ERR_PTR. The error
path for a vmalloc failure currently just returns NULL, triggering
a warning in ion_buffer_kmap_get. Encode the vmalloc failure as an ERR_PTR.

      n_tty: Fix stall at n_tty_receive_char_special(). · a1f75c3f
      Tetsuo Handa authored 
      commit 3d63b7e4 upstream.

syzbot is reporting stalls at n_tty_receive_char_special() [1]. This is
because comparison is not working as expected since ldata->read_head can
change at any moment. Mitigate this by explicitly masking with buffer size
when checking condition for "while" loops.

      USB: serial: cp210x: add Silicon Labs IDs for Windows Update · 216c5fab
      Karoly Pados authored 
      commit 2f839823 upstream.

Silicon Labs defines alternative VID/PID pairs for some chips that when
used will automatically install drivers for Windows users without manual
intervention. Unfortunately, these IDs are not recognized by the Linux
module, so using these IDs improves user experience on one platform but
degrades it on Linux. This patch addresses this problem.

      usb: cdc_acm: Add quirk for Uniden UBC125 scanner · 6f8b3fd2
      Houston Yaroschoff authored 
      commit 4a762569 upstream.

Uniden UBC125 radio scanner has USB interface which fails to work
with cdc_acm driver:
  usb 1-1.5: new full-speed USB device number 4 using xhci_hcd
  cdc_acm 1-1.5:1.0: Zero length descriptor references
  cdc_acm: probe of 1-1.5:1.0 failed with error -22

Adding the NO_UNION_NORMAL quirk for the device fixes the issue:
  usb 1-4: new full-speed USB device number 15 using xhci_hcd
  usb 1-4: New USB device found, idVendor=1965, idProduct=0018
  usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 1-4: Product: UBC125XLT

  usb 1-4: SerialNumber: 0001
  cdc_acm 1-4:1.0: ttyACM0: USB ACM device
