Subject: [PATCH v4] HID: quirks: Change manufacturer for 4c4a:4155
Based on available evidence, the USB ID 4c4a:4155 used by multiple
devices has been attributed to Jieli. The commit 1a8953f4f774
("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY") affected touchscreen
functionality. Added checks for manufacturer and serial number to
maintain microphone compatibility, enabling both devices to function
properly.
Fixes: 1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY")

Changes in v4:
-- add serial number. Since I saw JIELI using identical IDs for different
devices with distinct serial numbers, I worry SMARTLINKTECHNOLOGY might
reuse this ID for touchscreens. Adding serial number verification provides
extra insurance.
