Subject: HID: wacom: remove cleanup of wacom->remote_dir from wacom_clean_inputs()
X-Git-Tag: Ubuntu-5.4-5.4.0-11.14~9259^2^9~30
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=b62f6465ce1fcbfe4459eb9fd67566ced2a27994;p=mirror_ubuntu-focal-kernel.git

HID: wacom: remove cleanup of wacom->remote_dir from wacom_clean_inputs()

wacom->remote_dir has nothing to do with inputs, so better not magically
removing it when cleaning inputs.
