i3c/master: Fix uninitialized variable next_addr
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. Addresses-Coverity: ("Uninitialized scalar variable") Fixes: 9ad9a52cce28 ("i3c/master: introduce the mipi-i3c-hci driver") Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Nicolas Pitre <npitre@baylibre.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Link: https://lore.kernel.org/linux-i3c/20201124123504.396249-1-colin.king@canonical.com
