Andy Shevchenko authored
There are several places in the kernel that use functionality like basename(3) with the exception: in case of '/foo/bar/' we expect to get an empty string. Let's do it common helper for them. Signed-off-by:

Changing backlight intensity on an Akita (Sharp Zaurus C-1000) triggers WARN_ON message: WARNING: at drivers/gpio/gpiolib.c:1672 __gpio_set_value+0x38/0xa4() Modules linked in: Backtrace: corgi_bl_set_intensity+0x0/0x74 corgi_bl_update_status+0x0/0x64 corgi_lcd_probe+0x0/0x258 spi_drv_probe+0x0/0x24 driver_probe_device+0x0/0x208 __driver_attach+0x0/0x94 bus_for_each_dev+0x0/0x90 driver_attach+0x0/0x28 bus_add_driver+0x0/0x22c driver_register+0x0/0x134 spi_register_driver+0x0/0x60 corgi_lcd_driver_init+0x0/0x1c do_one_initcall+0x0/0x174 kernel_init+0x0/0x2a8 Akita machines have backlight controls hooked to a gpio expander chip, max7310 using i2c transfers which can sleep. In this case, pca953x_gpio_set_value() can be called to control gpio, and pca953x_setup_gpio() sets can_sleep flag. Therefore, gpio_set_value_cansleep() should be used in order to avoid WARN_ON on akita machines. Akita is the only exception in this case since other users of corgi_lcd access backlight gpio controls through a different gpio expander which does not set the can_sleep flag.

GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below: GPIOF_DIR_OUT (0 << 0) GPIOF_DIR_IN (1 << 0) So, when !pdata->reset_inverted is 1, the gpio pin can be set as input, instead of output. To prevent this problem, GPIOF_INIT flag should be used when using devm_gpio_request_one(). Signed-off-by:

Previously, when ops functions cannot be called, lcd_show_contrast() and lcd_store_contrast() returned 0, instead of ENXIO. Thus, in this case, a local variable 'rc' for return value should be initialized as ENXIO, after kstrtoul() is called. 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.
