      ACPI: consolidate functions in acpi ec driver · d7a76e4c
      Lennart Poettering authored
      Unify the following functions:
      
          acpi_ec_poll_read()
          acpi_ec_poll_write()
          acpi_ec_poll_query()
          acpi_ec_intr_read()
          acpi_ec_intr_write()
          acpi_ec_intr_query()
      
      into:
      
          acpi_ec_poll_transaction()
          acpi_ec_intr_transaction()
      
      These new functions take as arguments an ACPI EC command, a few bytes
      to write to the EC data register and a buffer for a few bytes to read
      from the EC data register. The old _read(), _write(), _query() are
      just special cases of these functions.
      
      Then unified the code in acpi_ec_poll_transaction() and
      acpi_ec_intr_transaction() a little more. Both functions are now just
      wrappers around the new acpi_ec_transaction_unlocked() function. The
      latter contains the EC access logic, the two original
      function now just do their special way of locking and call the the
      new function for the actual work.
      
      This saves a lot of very similar code. The primary reason for doing
      this, however, is that my driver for MSI 270 laptops needs to issue
      some non-standard EC commands in a safe way. Due to this I added a new
      exported function similar to ec_write()/ec_write() which is called
      ec_transaction() and is essentially just a wrapper around
      acpi_ec_{poll,intr}_transaction().
