5.15-stable review patch. If anyone has any objections, please let me know.

From: Zhang Heng zhangheng@kylinos.cn
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.
