2019-10-31rtw88: remove redundant null pointer check on arraysColin Ian King
The checks to see if swing_table->n or swing_table->p are null are redundant since n and p are arrays and can never be null if swing_table is non-null. I believe these are redundant checks and can be safely removed, especially the checks implies that these are not arrays which can lead to confusion.

2019-10-31rtw88: fix potential read outside array boundaryTzu-En Huang
The level of cckpd is from 0 to 4, and it is the index of array pd_lvl[] and cs_lvl[]. However, the length of both arrays are 4, which is smaller than the possible maximum input index. Enumerate cck level to make sure the max level will not be wrong if new level is added in future.

2019-10-31rtw88: rearrange if..else statements for rx rate indexesYan-Hsuan Chuang
Driver just memset() rx_status to 0 before assigning rate indexes. And driver could never hit the 'else' because the driver checks if 'pkt_stat->rate >= DESC_RATEMCS0', so the 'else' statement can be removed. Also rearrange the if..else statements because DESC_RATEMCS0 is actually larger than DESC_RATE1M ~ DESC_RATE54M, move the check of 'pkt_stat->rate >= DESC_RATEMCS0' to the last to keep an increasing order.

2019-10-25iwlwifi: dbg_ini: use vzalloc to allocate dumping memory regionsShahar S Matityahu
During dump flow, the driver allocates spaces to store the memory regions that will be included in the dump. These regions can be very large so in order to avoid allocation failure, use vzalloc instead. The kmalloc uses GFP_KERNEL and the driver does not make any use of the fact that the memory is contiguous so the same functionality is maintained.

2019-10-24net: core: add generic lockdep keysTaehee Yoo
Some interface types could be nested. (VLAN, BONDING, TEAM, MACSEC, MACVLAN, IPVLAN, VIRT_WIFI, VXLAN, etc..) These interface types should set lockdep class because, without lockdep class key, lockdep always warn about unexisting circular locking. In the current code, these interfaces have their own lockdep class keys and these manage itself. So that there are so many duplicate code around the /driver/net and /net/. This patch adds new generic lockdep keys and some helper functions for it. This patch does below changes. a) Add lockdep class keys in struct net_device - qdisc_running, xmit, addr_list, qdisc_busylock - these keys are used as dynamic lockdep key. b) When net_device is being allocated, lockdep keys are registered. - alloc_netdev_mqs() c) When net_device is being free'd llockdep keys are unregistered. - free_netdev() d) Add generic lockdep key helper function - netdev_register_lockdep_key() - netdev_unregister_lockdep_key() - netdev_update_lockdep_key() e) Remove unnecessary generic lockdep macro and functions f) Remove unnecessary lockdep code of each interfaces. After this patch, each interface modules don't need to maintain their lockdep keys. Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
