[PATCH 4/4] Input: tps6507x-ts - fix input device parent assignment

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Assigning the MFD parent device (tsc->dev) instead of the platform
device (&pdev->dev) as the parent device after
devm_input_allocate_device(&pdev->dev) splits devres management across
two devices. As a result, input_register_device() attaches the devm
unregistration action to the MFD parent device rather than the platform
device, leaving the input device registered when the platform driver
unbinds.

devm_input_allocate_device(&pdev->dev) already sets
input_dev->dev.parent to &pdev->dev. Drop the redundant and erroneous
assignment.

Fixes: 2e2a0db8c88d ("Input: tps6507x-ts - update to devm_* API")
