e5e66ed00e Input: tps6507x-ts - simplify function return logic
The invoked function already returns zero on success or a negative
errno code so there is no need to open code the logic in the caller.

This also fixes the following make coccicheck warning:

drivers/input/touchscreen/tps6507x-ts.c:57:5-8: WARNING: end returns can be simplified

A platform_driver does not need to set an owner, it will be populated by the
driver core.

There is no need to roll our own polling scheme when we already have
one implemented by the core.

22381288ba Input: tps6507x-ts - remove vref from platform data
Although defined in platform data, vref is not used anywhere.

Also remove model, irq, and clear_penirq as they are not used either.

1c1e864696 input/tps6507x-ts: use system_wq instead of dedicated workqueue
With cmwq, there's no reason to use a separate workqueue.  Drop
tps6507x_ts->wq and use system_wq instead.

Stanse found that tsc is dereferenced earlier than checked for being
NULL in tps6507x_ts_remove. Remove the test because there is no way
for tsc to be NULL there.

f7a2e30246 Input: tps6507x-ts - a couple work queue cleanups
1) Use msecs_to_jiffies() instead of calculating by hand.
2) Call cancel_delayed_work_sync() instead of cancel_delayed_work()
   followed by a separate flush_workqueue().
3) Remove the "tsc->wq = 0;"  Sparse complains about that because
   tsc->wq is a pointer, not an int.  It's not needed because we just
   free the pointer anyway.
