If anyone has any objections, please let me know. ------------------ From: Vadim Klishko [ Upstream commit 1c942462c3969b287a86ab6dbb143324289d564e ] Cirque touchpads with PID D0C1 generate an error when probed by the I2C HID driver, resulting in no hidraw device created. Adding I2C_HID_QUIRK_NO_IRQ_AFTER_RESET fixes the issue.
