• fd4a319bc   spi: Remove HOTPLUG section attributes ... Browse Code »

  CONFIG_HOTPLUG is going away as an option. As result the __dev*
  markings will be going away.

  Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
  and __devexit.

  Bill Pemberton has done most of the legwork on this series. I've used
  his script to purge the attributes from the drivers/gpio tree.

• f95e1028e   spi/mpc52xx: Fix device remove function ... Browse Code »

  The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is
  complete; it reduces the device reference count to zero, which results in
  device memory being freed. An extra call to spi_master_put is unnecessary
  and results in an access to free memory.

  At the same time, since the call to spi_unregister_master results in device
  memory being freed, it must no longer be accessed afterwards.

  To fix both problems, call spi_master_get to get an extra reference to the
  device, and call spi_master_put only after the last access to device data.

• 866c0f25d   spi/mpc52xx: Fix error handling in probe function ... Browse Code »

  The call to spi_master_put() is needed to free device memory. It must be called
  after spi_alloc_master, and must only be called after the device memory is no
  longer used.

• 1e8a52e18   spi: By default setup spi_masters with 1 chipselect and dynamics bus number ... Browse Code »

  Trivial simplification. Instead of requiring spi master drivers to
  always set the bus number (even when a dynamic number is desired),
  this patch modifies spi_alloc_master() to initialize num_chipselect to
  1 (because there will always be at least one CS) and bus_num to -1 for
  dynamic allocation. This simplifies the code needed to be written for
  drivers.

• 940ab8896   drivercore: Add helper macro for platform_driver boilerplate ... Browse Code »

  For simple modules that contain a single platform_driver without any
  additional setup code then ends up being a block of duplicated
  boilerplate. This patch adds a new macro, module_platform_driver(),
  which replaces the module_init()/module_exit() registrations with
  template functions.

• ca632f556   spi: reorganize drivers ... Browse Code »

  Sort the SPI makefile and enforce the naming convention spi_*.c for
  spi drivers.

  This change also rolls the contents of atmel_spi.h into the .c file
  since there is only one user of that particular include file.

  v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
  be the predominant pattern for subsystem prefixes.
  - Clean up filenames in Kconfig and header comment blocks
