2022-03-17net: mscc: ocelot: fix backwards compatibility with single-chain tc-flower ↵Vladimir Oltean
offload ACL rules can be offloaded to VCAP IS2 either through chain 0, or, since the blamed commit, through a chain index whose number encodes a specific PAG (Policy Action Group) and lookup number. The chain number is translated through ocelot_chain_to_pag() into a PAG, and through ocelot_chain_to_lookup() into a lookup number. The problem with the blamed commit is that the above 2 functions don't have special treatment for chain 0. So ocelot_chain_to_pag(0) returns filter->pag = 224, which is in fact -32, but the "pag" field is an u8. So we end up programming the hardware with VCAP IS2 entries having a PAG of 224. But the way in which the PAG works is that it defines a subset of VCAP IS2 filters which should match on a packet. The default PAG is 0, and previous VCAP IS1 rules (which we offload using 'goto') can modify it. So basically, we are installing filters with a PAG on which no packet will ever match. This is the hardware equivalent of adding filters to a chain which has no 'goto' to it. Restore the previous functionality by making ACL filters offloaded to chain 0 go to PAG 0 and lookup number 0. The choice of PAG is clearly correct, but the choice of lookup number isn't "as before" (which was to leave the lookup a "don't care"). However, lookup 0 should be fine, since even though there are ACL actions (policers) which have a requirement to be used in a specific lookup, that lookup is 0.

2022-03-17net: bcmgenet: skip invalid partial checksumsDoug Berger
The RXCHK block will return a partial checksum of 0 if it encounters a problem while receiving a packet. Since a 1's complement sum can only produce this result if no bits are set in the received data stream it is fair to treat it as an invalid partial checksum and not pass it up the stack.

2022-03-17bnx2x: fix built-in kernel driver load failureManish Chopra
Commit b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") added request_firmware() logic in probe() which caused load failure when firmware file is not present in initrd (below), as access to firmware file is not feasible during probe. Direct firmware load for bnx2x/bnx2x-e2-7.13.15.0.fw failed with error -2 Direct firmware load for bnx2x/bnx2x-e2-7.13.21.0.fw failed with error -2 This patch fixes this issue by - 1. Removing request_firmware() logic from the probe() such that .ndo_open() handle it as it used to handle it earlier 2. Given request_firmware() is removed from probe(), so driver has to relax FW version comparisons a bit against the already loaded FW version (by some other PFs of same adapter) to allow different compatible/close enough FWs with which multiple PFs may run with (in different environments), as the given PF who is in probe flow has no idea now with which firmware file version it is going to initialize the device in ndo_open() Link: https://lore.kernel.org/all/46f2d9d9-ae7f-b332-ddeb-b59802be2bab@molgen.mpg.de/ Reported-by: Paul Menzel <pmenzel@molgen.mpg.de> Tested-by: Paul Menzel <pmenzel@molgen.mpg.de> Fixes: b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") Signed-off-by: Manish Chopra <manishc@marvell.com> Signed-off-by: Ariel Elior <aelior@marvell.com> Link: https://lore.kernel.org/r/20220316214613.6884-1-manishc@marvell.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-03-17iwlwifi: mei: fix building iwlmeiArnd Bergmann
Building iwlmei without CONFIG_CFG80211 causes a link-time warning: ld.lld: error: undefined symbol: ieee80211_hdrlen >>> referenced by net.c >>> net/wireless/intel/iwlwifi/mei/net.o:(iwl_mei_tx_copy_to_csme) in archive drivers/built-in.a Add an explicit dependency to avoid this. In theory it should not be needed here, but it also seems pointless to allow IWLMEI for configurations without CFG80211.

2022-03-17cpufreq: powernow-k8: Re-order the init checksMario Limonciello
The powernow-k8 driver will do checks at startup that the current active driver is acpi-cpufreq and show a warning when they're not expected. Because of this the following warning comes up on systems that support amd-pstate and compiled in both drivers: `WTF driver: amd-pstate` The systems that support powernow-k8 will not support amd-pstate, so re-order the checks to validate the CPU model number first to avoid this warning being displayed on modern SOCs.

2022-03-17ACPI: bus: Avoid using CPPC if not supported by firmwareRafael J. Wysocki
If the platform firmware indicates that it does not support CPPC by clearing the OSC_SB_CPC_SUPPORT and OSC_SB_CPCV2_SUPPORT bits in the platform _OSC capabilities mask, avoid attempting to evaluate _CPC which may fail in that case. Because the OSC_SB_CPC_SUPPORT and OSC_SB_CPCV2_SUPPORT bits are only added to the supported platform capabilities mask on x86, when X86_FEATURE_HWP is supported, allow _CPC to be evaluated regardless in the other cases.

2022-03-17ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNUWerner Sembach
Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working native and video interface. However the default detection mechanism first registers the video interface before unregistering it again and switching to the native interface during boot. This results in a dangling SBIOS request for backlight change for some reason, causing the backlight to switch to ~2% once per boot on the first power cord connect or disconnect event. Setting the native interface explicitly circumvents this buggy behaviour by avoiding the unregistering process.

2022-03-17net: stmmac: clean up impossible conditionDan Carpenter
This code works but it has a static checker warning: drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:1687 init_dma_rx_desc_rings() warn: always true condition '(queue >= 0) => (0-u32max >= 0)' Obviously, it makes no sense to check if an unsigned int is >= 0. What prevents this code from being a forever loop is that later there is a separate check for if (queue == 0). The "queue" variable is less than MTL_MAX_RX_QUEUES (8) so it can easily fit in an int type. Any larger value for "queue" would lead to an array overflow when we assign "rx_q = &priv->rx_queue[queue]".

Making DRM_PANEL_EDP select DRM_KMS_HELPER resolves this problem. To avoid a resulting cyclic dependency with DRM_PANEL_BRIDGE, don't make the latter depend on DRM_KMS_HELPER and fix the one DRM bridge drivers that doesn't already select DRM_KMS_HELPER. As KMS helpers cannot be selected directly by the user, config symbols should avoid depending on it anyway.
