Subject: [PATCH v3] 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. A manufacturer check was added to maintain microphone
compatibility, enabling both devices to function properly.
Fixes: 1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY")
