2025-02-08net: phy: realtek: clear master_slave_state if link is downDaniel Golle
[ Upstream commit ea8318cb33e593bbfc59d637eae45a69732c5387 ] rtlgen_decode_physr() which sets master_slave_state isn't called in case the link is down and other than rtlgen_read_status(), rtl822x_c45_read_status() doesn't implicitely clear master_slave_state. Avoid stale master_slave_state by always setting it to MASTER_SLAVE_STATE_UNKNOWN in rtl822x_c45_read_status() in case the link is down.

However, in the loop where we try values of R, we should compare the derived `vco` with `target_vco_rate`. However, we were in fact comparing it with `target_rate`, which is actually after Q shift.

2025-02-08wifi: wilc1000: unregister wiphy only after netdev registrationAlexis Lothoré
[ Upstream commit 208dea9107e80a33dfeb029bdb93cb53eccf005d ] wiphy_unregister()/wiphy_free() has been recently decoupled from wilc_netdev_cleanup() to fix a faulty error path in sdio/spi probe functions.

Fix this warning by moving wiphy_unregister() after wilc_netdev_cleanup() is nominal paths (ie: driver removal). wilc_netdev_cleanup() ordering is left untouched in error paths in probe function because net device is not registered in those paths (so the warning can not trigger), yet the wiphy can still be registered, and we still some cleanup steps from wilc_netdev_cleanup().

2025-02-08wifi: ath12k: fix key cache handlingAditya Kumar Singh
[ Upstream commit 336097d74c284a7c928b723ce8690f28912da03d ] Currently, an interface is created in the driver during channel assignment. If mac80211 attempts to set a key for an interface before this assignment, the driver caches the key. Once the interface is created, the driver installs the cached key to the hardware. This sequence is exemplified in mesh mode operation where the group key is set before channel assignment. However, in ath12k_mac_update_key_cache(), after caching the key, due to incorrect logic, it is deleted from the cache during the subsequent loop iteration. As a result, after the interface is created, the driver does not find any cached key, and the key is not installed to the hardware which is wrong. This leads to issue in mesh, where broadcast traffic is not encrypted over the air. Fix this issue by adjusting the logic of ath12k_mac_update_key_cache() properly.

2025-02-08cpufreq: ACPI: Fix max-frequency computationGautham R. Shenoy
[ Upstream commit 0834667545962ef1c5e8684ed32b45d9c574acd3 ] Commit 3c55e94c0ade ("cpufreq: ACPI: Extend frequency tables to cover boost frequencies") introduced an assumption in acpi_cpufreq_cpu_init() that the first entry in the P-state table was the nominal frequency. This assumption is incorrect. The frequency corresponding to the P0 P-State need not be the same as the nominal frequency advertised via CPPC. Since the driver is using the CPPC.highest_perf and CPPC.nominal_perf to compute the boost-ratio, it makes sense to use CPPC.nominal_freq to compute the max-frequency. CPPC.nominal_freq is advertised on platforms supporting CPPC revisions 3 or higher. Hence, fallback to using the first entry in the P-State table only on platforms that do not advertise CPPC.nominal_freq.

[ Upstream commit f1b1e133a770fcdbd89551651232b034d2f7a27a ] When initializing the network card, unplugging the device will trigger an -EPROTO error, resulting in a flood of error messages being printed frantically. The exception is printed as follows： mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71 mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71 ... It will continue to print more than 2000 times for about 5 minutes, causing the usb device to be unable to be disconnected. During this period, the usb port cannot recognize the new device because the old device has not disconnected. There may be other operating methods that cause -EPROTO, but -EPROTO is a low-level hardware error. It is unwise to repeat vendor requests expecting to read correct data. It is a better choice to treat -EPROTO and -ENODEV the same way. Similar to commit 9b0f100c1970 ("mt76: usb: process URBs with status EPROTO properly") do no schedule rx_worker for urb marked with status set -EPROTO. I also reproduced this situation when plugging and unplugging the device, and this patch is effective. Just do not vendor request again for urb marked with status set -EPROTO.
