[PATCH][next] Input: qt1050: fix less than zero comparison on an unsigned int

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently the less than zero comparison of val is always false because
val is an unsigned int. Fix this by making val a signed int.

Addresses-Coverity: ("Unsigned compared against zero")
Fixes: a33ff45923c8 ("Input: qt1050 - add Microchip AT42QT1050 support")
