HID: picoLCD: Replace check_fb in favor of struct fb_info.lcd_dev

2024-09-30T15:49:42Z

Store the lcd device in struct fb_info.lcd_dev. The lcd subsystem can now detect the lcd's fbdev device from this field. This makes the implementation of check_fb in picolcd_lcdops obsolete. Remove it. Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Thompson Acked-by: Jiri Kosina Link: https://lore.kernel.org/r/20240906075439.98476-26-tzimmermann@suse.de Signed-off-by: Lee Jones

HID: picoLCD: Constify lcd_ops

2024-05-03T09:45:34Z

'struct lcd_ops' is not modified by core backlight code, so it can be made const for increased code safety. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Bruno Prémont Link: https://lore.kernel.org/r/20240424-video-backlight-lcd-ops-v2-15-1aaa82b07bc6@kernel.org Signed-off-by: Lee Jones

HID: picoLCD: Deletion of unnecessary checks before three function calls

2015-06-29T12:51:12Z

The functions backlight_device_unregister(), lcd_device_unregister() and rc_unregister_device() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Reviewed-by: Bruno Prémont Signed-off-by: Jiri Kosina

HID: use hid_hw_request() instead of direct call to usbhid

2013-02-25T12:26:41Z

This allows the hid drivers to be independent from the transport layer. The patch was constructed by replacing all occurences of usbhid_submit_report() by its hid_hw_request() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. Finally, few drivers still depends on USB_HID. Many of them are requiring the io wait callback. They are found in the next patch. Signed-off-by: Benjamin Tissoires Reviewed-by: Mika Westerberg For the sensor-hub part: Tested-by: Mika Westerberg Signed-off-by: Jiri Kosina

HID: picoLCD: split driver code

In order to make code maintenance easier, split the vairous functions into individial files (this removes a bunch of #ifdefs). Signed-off-by: Bruno Prémont Signed-off-by: Jiri Kosina
