backlight: grab ops_lock before testing bd->ops

2010-12-14T22:40:14+00:00

commit d1d73578e053b981c3611e5a211534290d24a5eb upstream. According to the comment describing ops_lock in the definition of struct backlight_device and when comparing with other functions in backlight.c the mutex must be hold when checking ops to be non-NULL. Fixes a problem added by c835ee7f4154992e6 ("backlight: Add suspend/resume support to the backlight core") in Jan 2009.

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58+00:00

I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

backlight: l4f00242t03: fix error handling in l4f00242t03_probe

2010-05-26T16:34:35+00:00

Error handling fixes: 1. In the case of kzalloc failure, simple return -ENOMEM instead of goto err. ( priv is NULL in this case ) 2. In the case of gpio_request fail for reset_gpio and data_enable_gpio, properly release resources by goto err and err2 respectively.

backlight: add S6E63M0 AMOLED LCD Panel driver

2010-05-26T16:34:16+00:00

This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI interface also almost features for lcd panel driver has been implemented in here. and I added new structure common for all the lcd panel drivers to include/linux/lcd.h file. LCD Panel driver needs interfaces for controlling device power such as power on/off and reset. these interfaces are device specific so it should be implemented to machine code at this time, we should create new structure for registering these functions as callbacks and also a header file for that structure and finally registered callback functions would be called by lcd panel driver. such header file(including new structure for lcd panel) would be added for all the lcd panel drivers. If anyone provides common structure for registering such callback functions then we could reduce unnecessary header files for lcd panel. I thought that suitable anyone could be include/linux/lcd.h so a new lcd_platform_data structure was added there.
