Since all the other call-sites of cros_ec_cmd_xfer() have been converted to use cros_ec_cmd_xfer_status() instead, update the remaining call-sites to prepare for the merge of cros_ec_cmd_xfer() into cros_ec_cmd_xfer_status(). As part of this update, change the error handling inside cros_ec_get_sensor_count() such that the legacy LPC interface is tried on all error values, not just when msg->result != EC_RESULT_SUCCESS. Note that there is a slight change in API in cros_ec_get_sensor_count(): it will return a negative number of sensors when there are no sensors on arm platform when MOTIONSENSE_CMD_DUMP is not supported (typical for sensorless chromebook) instead of 0. However, this is not a problem when probing the EC as we ignore errors only looking for cros_ec_get_sensor_count() returning a positive number of sensors.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
