Input: cyttsp5 - use %pe format specifier

The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR()

This patch fixes this cocci report:
./cyttsp5.c:927:3-10: WARNING: Consider using %pe to print PTR_ERR()
