[v2,00/17] platform/chrome: Replace cros_ec_cmd_xfer_status

Message

Prashant Malani Feb. 5, 2020, 6:59 p.m. UTC

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_cmd() 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.

Changes in v2:
- Renamed new function to cros_ec_cmd()
- Added a "result" pointer argument, for call-sites that are interested
  in the EC command result.
- Updated subsequent patches to new function name and parameter list.
- Used C99 element setting to initialize some structs directly rather
  than zeroing them, then setting them.
