Add a new field to led_classdev to save activattion state after activate routine is successful. This saved state is used in deactivate routine to do cleanup such as removing device files, and free memory allocated during activation. Currently trigger_data not being null is used for this purpose. Existing triggers will need changes to use this new field. Signed-off-by:

The advantage of kcalloc is that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107Signed-off-by:

led-class.c and ledtrig-timer.c still use simple_strtoul(). Change them to use kstrtoul() instead of obsolete simple_strtoul(). Also fix the existing int ret declaration to be ssize_t to match the return type for _store functions in ledtrig-timer.c. Signed-off-by:

Gcc 4.6.2 complains that: drivers/leds/leds-lp5521.c: In function `lp5521_load_program': drivers/leds/leds-lp5521.c:214:21: warning: `mode' may be used uninitialized in this function [-Wuninitialized] drivers/leds/leds-lp5521.c: In function `lp5521_probe': drivers/leds/leds-lp5521.c:788:5: warning: `buf' may be used uninitialized in this function [-Wuninitialized] drivers/leds/leds-lp5521.c:740:6: warning: `ret' may be used uninitialized in this function [-Wuninitialized] These are real problems if lp5521_read() returns an error. When that happens we should handle it, instead of ignoring it or doing a bitwise OR with all the other error codes and continuing. Signed-off-by:

This patchset adds early fb blank feature that a callback of lcd panel driver is called prior to specific fb driver's one. In the case of MIPI-DSI based video mode LCD Panel, for lcd power off, the power off commands should be transferred to lcd panel with display and mipi-dsi controller enabled because the commands is set to lcd panel at vsync porch period. and in opposite case, the callback of fb driver should be called prior to lcd panel driver's one because of same issue. Also if fb_blank mode is changed to FB_BLANK_POWERDOWN then display controller would be off(clock disable) but lcd panel would be still on. at this time, you could see some issue like sparkling on lcd panel because video clock to be delivered to ldi module of lcd panel was disabled. this issue could occurs for all lcd panels. The callback order is as the following: at fb_blank function of fbmem.c -> fb_notifier_call_chain(FB_EARLY_EVENT_BLANK) -> lcd panel driver's early_set_power() -> info->fbops->fb_blank() -> spcefic fb driver's fb_blank() -> fb_notifier_call_chain(FB_EVENT_BLANK) -> lcd panel driver's set_power() -> fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) if info->fops->fb_blank() was failed. fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) would be called to revert the effects of previous FB_EARLY_EVENT_BLANK call. and note that if early_set_power() of lcd_ops is NULL then early fb blank callback would be ignored. This patch: Add early_set_power and r_early_set_power callbacks. early_set_power callback is called prior to fb_blank() of fbmem.c and r_early_set_power callback is called if fb_blank() was failed to revert the effects of the early_set_power call of lcd panel driver.

Add FB_EARLY_EVENT_BLANK and FB_R_EARLY_EVENT_BLANK event mode supports. first, fb_notifier_call_chain() is called with FB_EARLY_EVENT_BLANK and fb_blank() of specific fb driver is called and then fb_notifier_call_chain() is called with FB_EVENT_BLANK again at fb_blank(). and if fb_blank() was failed then fb_nitifier_call_chain() would be called with FB_R_EARLY_EVENT_BLANK to revert the previous effects.

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by:
