• 751c925cb   spi/omap: call pm_runtime_disable in error path and remove ... Browse Code »

  omap mcspi probe() doesnt call pm_runtime disable functions
  in case of failure. remove() doesnt call pm_runtime disable. This could
  lead to warnings as below on subsequent insmod.

  ~# insmod spi-omap2-mcspi.ko
  [ 255.383671] omap2_mcspi omap2_mcspi.1: Unbalanced pm_runtime_enable!
  ...

  This patch adds the pm_runtime disable() at appropriate stages.

• 1458d160d   OMAP: SPI: Fix the trying to free nonexistent resource error ... Browse Code »

  Currently there is a request_mem_region(r->start, ..
  followed by r->start += pdata->regs_offset;

  And then in remove

  r = platform_get_resource(pdev, IORESOURCE_MEM, 0);
  release_mem_region(r->start, resource_size(r));

  Here the offset addition is not taken care. Fix the code for the
  same.

  Done via coccinelle scripts like:

  @@
  struct resource *ptr;
  @@

  - ptr->end - ptr->start + 1
  + resource_size(ptr)

  and some grep and typing.

  Mostly uncompiled, no cross-compilers.

• 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
