Dan Carpenter 73dc99c0ea Bluetooth: btrtl: Prevent potential NULL dereference ... [ Upstream commit 324dddea32 ] The btrtl_initialize() function checks that rtl_load_file() either had an error or it loaded a zero length file. However, if it loaded a zero length file then the error code is not set correctly. It results in an error pointer vs NULL bug, followed by a NULL pointer dereference. This was detected by Smatch: drivers/bluetooth/btrtl.c:592 btrtl_initialize() warn: passing zero to 'ERR_PTR' Fixes: 26503ad25d ("Bluetooth: btrtl: split the device initialization into smaller parts") Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2025-05-02 07:40:59 +02:00
