Use dev_err() to output errors instead of dev_dbg().

input_allocate_device uses kzalloc and it will emit a
standardized OOM message along with a dump_stack()
so this dev_err/dev_dbg is redundant and not necessary.

I saw you sent a big patchset changing this for all drivers.
Should I drop this patch?
