unbalanced local_bh_disable

[Johannes Berg]

Hi Dan,

I'm seeing things like this with sparse:

drivers/net/wireless/intel/iwlwifi/pcie/rx.c:1746 iwl_pcie_irq_handler() warn: 
returning with unbalanced local_bh_disable
drivers/net/wireless/intel/iwlwifi/pcie/rx.c:1992 iwl_pcie_irq_msix_handler() 
warn: returning with unbalanced local_bh_disable

but the code looks like

                local_bh_disable();
                iwl_pcie_rx_handle(trans, 0);
                local_bh_enable();

Any idea what's confusing smatch?

Thanks,
johannes
