HID: quirks: work around VID/PID conflict for 0x4c4a/0x4155
commit beab067dbcff642243291fd528355d64c41dc3b2 upstream.
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.
