# \[PATCH\] HID: picolcd\_core: Remove setting hdev-\>claimed before calling hid\_hw\_start() - Subsystems: HID CORE LAYER, PICOLCD HID DRIVER, THE REST - Maintainers: Jiri Kosina, Benjamin Tissoires, Bruno Prémont, Linus Torvalds - List: linux-input - 2 messages, 2 authors - Page: https://ratatoskr.run/linux-input/2012/09/8920196/t ## \[PATCH\] HID: picolcd\_core: Remove setting hdev-\>claimed before calling hid\_hw\_start() - From: Axel Lin \ - Date: 2012-09-13 22:15:42 - Message: https://ratatoskr.run/linux-input/2012/09/8920196.md ```text Current implementation of hid_hw_start() allows connect_mask to be 0. Setting hdev->claimed = HID_CLAIMED_INPUT before calling hid_hw_start() is not necessary. Remove it.

I will what else (of 3.5 -> 3.6 changes) might have been lost while applying driver code split. Thanks for spotting.
