Hello Glen Lee,
This is a semi-automatic email about new static checker warnings.
The patch ec62e6d1ec3f: "staging: wilc1000: wilc_send_config_pkt:
pass struct wilc" from Nov 18, 2015, leads to the following Smatch
complaint:
drivers/staging/wilc1000/host_interface.c:356 handle_set_wfi_drv_handler()
warn: variable dereferenced before check 'hif_drv' (see line 353)
drivers/staging/wilc1000/host_interface.c
352
353 result = wilc_send_config_pkt(hif_drv->wilc, SET_CFG, &wid, 1,
^^^^^^^^^^^^^
Patch adds a dereference.
354 hif_drv_handler->handler);
355
356 if (!hif_drv)
^^^^^^^
Old check.
Recent patch 31f0f697dddd ("staging: wilc1000: wilc_set_wfi_drv_handler: pass vif index") will fix this issue
since we changed hif_drv with hif_drv_handler->handler to check deinit.
