Not all devices using this driver are backed by a PCI device, so it's not fair to assume 'to_pci_dev()' is valid. Fortunately, we only were using this to convert straight back to a bare 'device', which means we were only doing no-op pointer arithmetic, and not actually accessing potentially out-of-bounds memory. But this is still bad practice. Just use 'ar->dev' directly, since that's really all we're looking for. Fixes: 209b2a68 ("ath10k: add platform regulatory domain support") Signed-off-by:

Commit 2ea9f12c ("ath10k: add new cipher suite support") added a new n_cipher_suites HW param with a fallback value and a warning log. Commit 03a72288 ("ath10k: wmi: add hw params entry for wcn3990") later added WCN3990 HW entries, but it missed the n_cipher_suites. Rather than seeing this warning every boot ath10k_snoc 18800000.wifi: invalid hw_params.n_cipher_suites 0 let's provide the appropriate value.

Similar to regulator error handling, we should only start tearing down the 'i - 1' clock when clock 'i' fails to enable. Otherwise, we might end up with an unbalanced clock, where we never successfully enabled the clock, but we try to disable it anyway.

I rarely see drivers specify precise voltage requirements like this, but if we really have to...let's at least give a little wiggle room. Board designs (and accompanying device trees) may not provide exactly the voltage listed here, and we shouldn't fail to probe just because of this. Round these ranges down to the nearest volt, and provide a 0.05V margin. The regulator should provide its own supported ranges, which will helpfully intersect with these ranges. I would just as well remove these ranges entirely, but if I understand correctly, there's some reason that QCOM SoC's like to set zero / non-zero voltages. Signed-off-by:

If a regulator fails to set its voltage, we end up with an unbalanced call to regulator_disable(), because the error path starts with the current regulator (which was never enabled). Factor out the "on" function to perform (and unwind if failed) a single regulator at a time, and then main loop (ath10k_snoc_vreg_on()) can just worry about unwinding the regulators that were already enabled. It also helps to factor out the "off" function, to avoid repeating some code here. Signed-off-by:

wil6210 used to notify cfg80211_del_sta on every fw disconnect event. In disable_ap_sme mode the userspace manages the protocol SME and FW sends disconnect event only due to link loss.

With current reset flow, Talyn sometimes get stuck causing PCIe enumeration to fail. Fix this by removing some reset flow operations that are not relevant for Talyn. Setting bit 15 in RGF_HP_CTRL is WBE specific and is not in use for all wil6210 devices. For Sparrow, BIT_HPAL_PERST_FROM_PAD and BIT_CAR_PERST_RST were set as a WA an HW issue. Signed-off-by:

I had a couple concerns with this code. First, we definitely need to set the error code if the kzalloc() fails. Secondly, I was worried that if we didn't set "arsta->tx_stats" to NULL after freeing it, then it looks to me like it might lead to a use after free. I can't test that, but it's harmless to set it to NULL so I did. Fixes: a904417f ("ath10k: add extended per sta tx statistics support") Signed-off-by:

The host driver currently expects the channel info event to be received in pairs for all the channels, i.e. the first chan_info event for a particular channel will not have the COMPLETE flag set and the second chan_info event for the same channel will have the COMPLETE flag set. The HL2.0 firmware sends only one channel info event per channel which is scanned without the COMPLETE flag set. After sending the chan_info_event for all the channels, the HL2.0 firmware sends a chan_info_event with COMPLETE flag set to indicate the completion of the channel info event. The firmware does not indicate this behavior with any service bitmap and hence a new firmware feature flag is used to handle the modified parsing of the channel info events, in the host driver, for the firmware which sends single channel info event per scanned channel.
