wireless-drivers fixes for 5.1
Third set of fixes for 5.1. iwlwifi * fix an oops when creating debugfs entries * fix bug when trying to capture debugging info while in rfkill * prevent potential uninitialized memory dumps into debugging logs * fix some initialization parameters for AX210 devices * fix an oops with non-MSIX devices * fix an oops when we receive a packet with bogus lengths * fix a bug that prevented 5350 devices from working * fix a small merge damage from the previous series mwifiex * fig regression with resume on SDIO ath10k * fix locking problem with crashdump * fix warnings during suspend and resume -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJcyGH/AAoJEG4XJFUm622b3AIH/R/Af8W3E69s1jLpbwVpcnKX jucK1WePDwgTttUI4cmtpCIlLImTiiMxgWd+ku7tpwz4kMJWY8KOjrvwN3ulNGUr R0Vbsyc/CXS41DtfZt8IpckF3ru1omtdmBTfMEermoPbZZNtx1j34Odkn0VtEcjW 7Ml7u6YfZc/tKgWmIO6afhqMRgnChWGhK76ayCF7/9YM17uSoGw+rdLIM8o20+jE VwMbhvNuZILwTZ35mbi1Tnbz8dZr/1J7yMqrmfuZFkpLseWixcQ6zK53A8PTJ0Cf 6B+fiu7+9mUzNaqzuemlYrZ2PsGXprdjrBNaHcnRrc3+GZlilKcDFQQCPWrpmz8= =WiMH -----END PGP SIGNATURE----- Merge tag 'wireless-drivers-for-davem-2019-04-30' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers Kalle Valo says: ==================== wireless-drivers fixes for 5.1 Third set of fixes for 5.1. iwlwifi * fix an oops when creating debugfs entries * fix bug when trying to capture debugging info while in rfkill * prevent potential uninitialized memory dumps into debugging logs * fix some initialization parameters for AX210 devices * fix an oops with non-MSIX devices * fix an oops when we receive a packet with bogus lengths * fix a bug that prevented 5350 devices from working * fix a small merge damage from the previous series mwifiex * fig regression with resume on SDIO ath10k * fix locking problem with crashdump * fix warnings during suspend and resume Also note that this pull conflicts with net-next. And I want to emphasie that it's really net-next, so when you pull this to net tree it should go without conflicts. Stephen reported the conflict here: https://lkml.kernel.org/r/20190429115338.5decb50b@canb.auug.org.au In iwlwifi oddly commit154d4899e4
adds the IS_ERR_OR_NULL() in wireless-drivers but commitc9af7528c3
removes the whole check in wireless-drivers-next. The fix is easy, just drop the whole check for mvmvif->dbgfs_dir in iwlwifi/mvm/debugfs-vif.c, it's unneeded anyway. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
