This function finds the struct backlight_device for a given device tree node. A dummy function is provided so that it safely compiles out if OF support is disabled. [akpm@linux-foundation.org: Don't use IS_ENABLED(CONFIG_OF)] Signed-off-by:

devm_kfree() allocates memory that is released when a driver detaches. Thus, there is no reason to explicitly call devm_kfree in probe or remove functions. Signed-off-by:

The mutex for accessing lp855x registers is used in case of the user-space interaction. When the brightness is changed via sysfs, the mutex is required. But the backlight class device already provides it. Thus, the lp855x mutex is unnecessary. Signed-off-by:

Kim, Milo authored
The LP855x family devices support the PWM input for the backlight control. Period of the PWM is configurable in the platform side. Platform specific functions are unnecessary anymore because generic PWM functions are used inside the driver. (PWM input mode) To set the brightness, new lp855x_pwm_ctrl() is used. If a PWM device is not allocated, devm_pwm_get() is called. The PWM consumer name is from the chip name such as 'lp8550' and 'lp8556'. To get the brightness value, no additional handling is required. Just the value of 'props.brightness' is returned. If the PWM driver is not ready while initializing the LP855x driver, it's OK. The PWM device can be retrieved later, when the brightness value is changed. Documentation is updated with an example.

By using devm_gpio_request_one it is possible to set the direction and initial value in one shot. Thus, using devm_gpio_request_one can make the code simpler. Signed-off-by:

Documentation/printk-formats.txt says to use %zd for a ssize_t argument and some drivers do. Unfortunately this prints a positive number for negative values eg: tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error 4294967234 Add a case to va_args a ssize_t type if the interpretation should be signed.

The boot_delay parameter affects all printk(), even if the log level prevents visible output from the call. It results in delays greater than the user intended without purpose. This patch changes the behaviour of boot_delay to only delay output. Signed-off-by:
