[PATCH] HID: wiimote: change wiimote_cmd_map_mp() to return void
From: Ethan Tidmore
Date: Sun Feb 15 2026 - 22:20:29 EST
The function wiimote_cmd_map_mp() returns bool but no variable is ever
assigned to its return value. Also, by it returning bool it causes a
signedness warning from Smatch because wiimote_cmd_write() can return
-EIO.
Detected by Smatch:
drivers/hid/hid-wiimote-core.c:510 wiimote_cmd_map_mp() warn:
signedness bug returning '(-512)'
