Subject: [PATCH 00/17] platform/chrome: Replace cros_ec_cmd_xfer_status
Date: Thu, 30 Jan 2020 12:30:31 -0800	[thread overview]
Message-ID: <20200130203106.201894-1-pmalani@chromium.org> (raw)

Many callers of cros_ec_cmd_xfer_status() use similar setup and cleanup
code, including setting up the cros_ec_command message struct and
copying the received buffer.

This series introduces a replacement function cros_ec_send_cmd_msg() that
performs this setup and teardown, and then updates all call sites that
used xfer_status() to use the new function instead.

The final patch in the series drops cros_ec_cmd_xfer_status() altogether.

Prashant Malani (17):
  platform/chrome: Add EC command msg wrapper
  platform/chrome: chardev: Use send_cmd_msg()
  platform/chrome: proto: Use send_cmd_msg
  platform/chrome: usbpd_logger: Use cmd_send_msg()
  platform/chrome: sensorhub: Use send_cmd_msg()
  platform/chrome: debugfs: Use send_cmd_msg()
  platform/chrome: sysfs: Use send_cmd_msg()
  extcon: cros_ec: Use cros_ec_send_cmd_msg()
  hid: google-hammer: Use cros_ec_send_cmd_msg()
  iio: cros_ec: Use cros_ec_send_cmd_msg()
  ASoC: cros_ec_codec: Use cros_ec_send_cmd_msg()
  power: supply: cros: Use cros_ec_send_cmd_msg()
  pwm: cros-ec: Remove cros_ec_cmd_xfer_status()
  rtc: cros-ec: Use cros_ec_send_cmd_msg()
  media: cros-ec-cec: Use cros_ec_send_cmd_msg()
  i2c: cros-ec-tunnel: Use cros_ec_send_cmd_msg()
  platform/chrome: Drop cros_ec_cmd_xfer_status()
