rtlwifi: Fix possible NULL dereference

Browse source

In drivers/net/wireless/rtlwifi/pci.c::_rtl_pci_rx_interrupt() we call
dev_alloc_skb(), which may fail and return NULL, but we do not check the
returned value against NULL before dereferencing the returned pointer.
This may lead to a NULL pointer dereference which means we'll crash - not
good.

In a separate call to dev_alloc_skb(), the debug level is changed so that
the failure message will always be logged.
