[PATCH 5.3 063/180] rtlwifi: rtl8192de: Fix missing code to retrieve RX buffer address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>

commit 0e531cc575c4e9e3dd52ad287b49d3c2dc74c810 upstream.

In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for
new drivers"), a callback to get the RX buffer address was added to
the PCI driver. Unfortunately, driver rtl8192de was not modified
appropriately and the code runs into a WARN_ONCE() call. The use
of an incorrect array is also fixed.

Fixes: 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for new drivers")
