-Subject: [PATCH] ath10k: Fix NULL pointer dereference in AHB device probe
-
-This fixes a NULL pointer dereference in the probe path for AHB devices.
-There attr parameter in the ath10k_ce_alloc_pipe() function is not
-initialized, but accessed. This function is called by
-ath10k_pci_setup_resource() which is called by ath10k_ahb_probe().
-
-The struct ath10k_pci is also used for AHB devices and not only for PCI
-devices.
-
-The initialization of the new members of struct ath10k_pci is moved to
-ath10k_pci_setup_resource() which is used by the PCI and the AHB code.
-
-This also fixes a use after free bug in ath10k_pci_remove() when ar_pci
-is accessed after ath10k_core_destroy() was called, which calls
-ieee80211_free_hw() and frees this memory.
-
-This fixes the following bug seen with backports-5.8-rc2 on OpenWrt on a
-IPQ4019 device:
