| Subject: [PATCH] HID: i2c-hid: fix no irq after reset on raydium 3118 |
| |
| commit 0c8432236dea20a95f68fa17989ea3f8af0186a5 upstream. |
| |
| On some ThinkPad L390 some raydium 3118 touchscreen devices |
| doesn't response any data after reset, but some does. |
| |
| Add this ID to no irq quirk, |
| then don't wait for any response alike on these touchscreens. |
| All kinds of raydium 3118 devices work fine. |
