Subject: USB: input: appletouch.c: fix up dev_err() usage
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=80f8594f63dd35179235aa22901dfa5ce786fe00;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

USB: input: appletouch.c: fix up dev_err() usage

We should always reference the input device for dev_err(), not the USB
device.  Fix up the places where I got this wrong.
