      acpi,msi-laptop: Fall back to EC polling mode for MSI laptop specific EC commands · 00eb43a1
      Lennart Poettering authored
      The ACPI EC that is used in MSI laptops knows some non-standard
      commands for changing the screen brighntess and a few other things,
      which are used by the msi-laptop.c driver. Unfortunately for these
      commands no GPE events for IBF and OBF are triggered. Since nowadays
      the EC code uses the ec_intr=1 mode by default, this causes these
      operations to timeout, although they don't fail. In result, all
      operations that you can do with the msi-laptop.c driver take more or
      less 1s to complete, which is awfully slow.
      In one of the more recent kernels (2.6.20?) the EC subsystem has been
      revamped. With that change the EC timeout has been increased. before
      that increase the MSI EC accesses were slow -- but not *that* slow,
      hence I took notice of this limitation of the MSI EC hardware only very
      The standard EC operations on the MSI EC as defined in the ACPI spec
      support GPE events properly.
      The following patch adds a new argument "force_poll" to the
      ec_transaction() function (and friends). If set to 1, the function
      will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the
      current behaviour is used. The msi-laptop driver is modified to make
      use of this new flag, so that OBF/IBF is polled for the special MSI EC
      transactions -- but only for them.

      Cosmetic only.
      Except in a single case, #define ACPI_*_DRIVER_NAME
      were invoked 0 or 1 times.

      It was erroneously used as a description rather than a name.
      ie. turn this:
      lenb@se7525gp2:/sys> ls bus/acpi/drivers
      ACPI AC Adapter Driver  ACPI Embedded Controller Driver  ACPI Power Resource Driver
      ACPI Battery Driver     ACPI Fan Driver                  ACPI Processor Driver

      ACPI: clean up ACPI_MODULE_NAME() use · f52fd66d
      Len Brown authored
      cosmetic only
      Make "module name" actually match the file name.
      Invoke with ';' as leaving it off confuses Lindent and gcc doesn't care.
      Fix indentation where Lindent did get confused.
