The patch titled Subject: drivers/leds/leds-lp5521.c: add 'update_config' in the lp5521_platform_data has been removed from the -mm tree. Its filename was leds-lp5521-add-update_config-in-the-lp5521_platform_data.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: "Kim, Milo" <Milo.Kim@xxxxxx> Subject: drivers/leds/leds-lp5521.c: add 'update_config' in the lp5521_platform_data The value of CONFIG register(Addr 08h) is configurable. For supporting this feature, update_config is added in the platform data. If 'update_config' is not defined, the default value is 'LP5521_PWRSAVE_EN | LP5521_CP_MODE_AUTO | LP5521_R_TO_BATT'. To define CONFIG register in the platform data, the bit definitions were mo= ved to the header file. Documentation updated : description about 'update_config' and example.
