Hi Greg,

Here's an update for drivers/mcb for 6.15 from Haoxiang Li fixing a double free in an error path in chameleon_parse_gdd().

In chameleon_parse_gdd(), if mcb_device_register() fails, 'mdev' would be released in mcb_device_register() via put_device(). Thus, goto 'err' label and free 'mdev' again causes a double free. Just return if mcb_device_register() fails.
