if output->wm_num is bigger than 2, the value for reg is not initialized, as warned by smatch: drivers/media/platform/qcom/camss-8x16/camss-vfe.c:633 vfe_set_xbar_cfg() error: uninitialized symbol 'reg'. drivers/media/platform/qcom/camss-8x16/camss-vfe.c:637 vfe_set_xbar_cfg() error: uninitialized symbol 'reg'. That shouldn't happen in practice, so add a logic that will break the loop if i > 1, fixing the warnings.
