[PATCH v3 0/5] (Set 2/2) Rid W=1 issues from Input

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

This is the second (and last) of 2 sets.

v3:
 - Make use of 'ret' instead of removing it
 - Use __always_unused instead of removing unused variables
 - Fix recent/new warning regarding undocumented 'prop' param
 
v2:
 - Replace empty if() with commentary
   - Suggested-by: Joe Perches


Lee Jones (5):
  input: mouse: synaptics: Replace NOOP with suitable commentary
  input: touchscreen: melfas_mip4: Mark a bunch of variables as
    __always_unused
  input: touchscreen: usbtouchscreen: Actually check return value of
    usb_submit_urb()
  input: touchscreen: surface3_spi: Remove set but unused variable
    'timestamp'
  input: touchscreen: stmpe-ts: Add description for 'prop' struct member
