Input: egalax_ts_serial - fix potential NULL dereference on error
We didn't check input_allocate_device() for failures so it could lead to a NULL deref. Fixes: 6b0f8f9c52ef ('Input: add eGalaxTouch serial touchscreen driver') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
