Hello Xinming Hu,
This is a semi-automatic email about new static checker warnings.
The patch 99074fc1e67b: "mwifiex: enable pcie MSIx interrupt mode
support" from Jan 11, 2016, leads to the following Smatch complaint:
drivers/net/wireless/marvell/mwifiex/pcie.c:2780 mwifiex_unregister_dev()
warn: variable dereferenced before check 'card' (see line 2777)
drivers/net/wireless/marvell/mwifiex/pcie.c
2776 const struct mwifiex_pcie_card_reg *reg;
2777 struct pci_dev *pdev = card->dev;
^^^^^^^^^
New dereference.
2778 int i;
2779
2780 if (card) {
^^^^
Old check.
2781 if (card->msix_enable) {
2782 for (i = 0; i < MWIFIEX_NUM_MSIX_VECTORS; i++)
regards,
dan carpenter
