leds/led-class: Add missing put_device()

2015-10-22T21:49:19Z

commit e5b5a61fcb3743f1dacf9e20d28f48423cecf0c1 upstream. Devices found by class_find_device must be freed with put_device(). Otherwise the reference count will not work properly.

leds:lp55xx: Correct Kconfig dependency for f/w user helper

2015-10-22T21:49:19Z

commit 2338f73d407d5abe2036d92716ba25ef5279c3d2 upstream. The commit [b67893206fc0: leds:lp55xx: fix firmware loading error] tries to address the firmware file handling with user helper, but it sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.

leds:lp55xx: fix firmware loading error

2015-06-29T17:10:57Z

LP55xx driver uses not firmware file but raw data to load program through the firmware interface.(Documents/leds/leds-lp55xx.txt) For example, here is how to run blinking green channel pattern. (The second engine is seleted and MUX is mapped to 'RGB' mode) echo 2 > /sys/bus/i2c/devices/xxxx/select_engine echo "RGB" > /sys/bus/i2c/devices/xxxx/engine_mux echo 1 > /sys/class/firmware/lp5562/loading echo "4000600040FF6000" > /sys/class/firmware/lp5562/data echo 0 > /sys/class/firmware/lp5562/loading echo 1 > /sys/bus/i2c/devices/xxxx/run_engine However, '/sys/class/firmware/' is not created after the firmware loader user helper was introduced. This feature is used in the case below. As soon as the firmware download is requested by the driver, firmware class subsystem tries to find the binary file. If it gets failed, then it just falls back to user helper to load raw data manually. Here, you can see the device file under /sys/class/firmware/. To make it happen, LP55xx driver requires two configurations. 1. Enable CONFIG_FW_LOADER_USER_HELPER_FALLBACK in Kconfig 2. Set option, 'FW_OPT_USERHELPER' on requesting the firmware data. It means the second option should be 'false' in request_firmware_nowait(). This option enables to load firmware data manually by calling fw_load_from_user_helper().
