Marko Katic 1581b088fc backlight: corgi_lcd: Use gpio_set_value_cansleep() to avoid WARN_ON ... 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.
