backlight: ili9320: Use lcd power constants

2024-09-30T15:49:41+00:00

Replace FB_BLANK_ constants with their counterparts from the
lcd subsystem. The values are identical, so there's no change
in functionality.

backlight: ili9320: Constify lcd_ops

2024-05-03T09:45:06+00:00

'struct lcd_ops' is not modified by core backlight code, so it can be
made const for increased code safety.

video: backlight: ili9320: Make ili9320_remove() return void

2021-10-20T14:13:59+00:00

Up to now ili9320_remove() returns zero unconditionally. Make it return
void instead which makes it easier to see in the callers that there is
no error to handle.

Also the return value of spi remove callbacks is ignored anyway.

backlight: ili9320: remove unnecessary OOM messages

2014-04-03T23:21:10+00:00

The site-specific OOM messages are unnecessary, because they duplicate
the MM subsystem generic OOM message.

backlight: use dev_get_platdata()

2013-11-13T03:09:16+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.  This is a cosmetic change to
make the code simpler and enhance the readability.

backlight: vgg2432a4: convert vgg2432a4_driver to dev_pm_ops

2013-04-30T01:28:18+00:00

Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management. Also, use of
pm_message_t is deprecated. Thus, it is removed.

2013-04-30T01:28:18+00:00

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

drivers/video/backlight/vgg2432a4.c: add missing const

2012-12-18T01:15:16+00:00

Add 'const' to static array that was missing it in its definition.  Also,
'const' is added to ili9320_write_regs(), because it is called by
vgg2432a4 driver.
