• ef7906f32   jz4740-battery: Fix signedness bug ... Browse Code »

  wait_for_completion_interruptible_timeout() may return negative value.
  In this case, checking if (t > 0) will return true if t is unsigned.

• 300bac7fb   power_supply: Convert drivers/power/* to use module_platform_driver() ... Browse Code »

  This patch converts the drivers in drivers/power/* to use the
  module_platform_driver() macro which makes the code smaller and a bit
  simpler.

• e9300066b   jz4740: silence warnings related to mfd_get_cell changes ... Browse Code »

  mfd_get_cell returns a const, so change the jz4740 clients to store
  a const mfd cell. This silences type mismatch warnings.

• 6a54ac214   mfd: mfd_cell is now implicitly available to jz4740 drivers ... Browse Code »

  No need to explicitly set the cell's platform_data/data_size.

  Modify clients to use mfd_get_cell helper function instead of
  accessing platform_data directly.

• f3dcab70e   jz4740-battery: Should include linux/io.h ... Browse Code »

  During test-build (with disabled 'depends on') I found that
  jz4740-battery driver lacks linux/io.h, which makes build break
  like this (on x86):

  CC [M] drivers/power/isp1704_charger.o
  jz4740-battery.c: In function 'jz_battery_read_voltage':
  jz4740-battery.c:84: error: implicit declaration of function 'readw’
  jz4740-battery.c: In function 'jz_battery_probe':
  jz4740-battery.c:284: error: implicit declaration of function 'ioremap_nocache’
  jz4740-battery.c:285: warning: assignment makes pointer from integer without a cast
  jz4740-battery.c:372: error: implicit declaration of function 'iounmap'
  make[2]: *** [drivers/power/jz4740-battery.o] Error 1

  This patch fixes the issues, and thus makes it easier to build-test
  the driver for me.

• 8477cedb4   jz4740-battery: Check if platform_data is supplied ... Browse Code »

  Currently platform_data is dereferenced without checking whether it
  is actually set, which can lead to kernel crashes.
  This patch adds a check which will abort the drivers probe function
  gracefully if no platform_data is supplied.

  We can not handle more then one ADC request at a time to the battery.
  The patch adds a mutex around the ADC read code to ensure this.
