| |
From: Colin Ian King <colin.king@canonical.com>
The variable next_addr is not initialized and is being used in a call to i3c_master_get_free_addr as a starting point to find the next address. Fix this by initializing next_addr to 0 to avoid an uninitialized garbage starting address from being used.
