In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for

never set.
In addition, there are several places when enable/disable interrupts
were commented out are restored. A sychronize_interrupts() call is

In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for
new drivers"), a callback to get the RX buffer address was added to
the PCI driver. Unfortunately, driver rtl8192de was not modified
appropriately and the code runs into a WARN_ONCE() call. The use
of an incorrect array is also fixed.

irqreturn_t type is an enum and in this context it's unsigned, so "err"
can't be irqreturn_t or it breaks the error handling. In fact the "err"
variable is only used to store integers (never irqreturn_t) so it should
be declared as int.
I removed the initialization because it's not required. Using a bogus
initializer turns off GCC's uninitialized variable warnings. Secondly,
there is a GCC warning about unused assignments and we would like to
enable that feature eventually so we have been trying to remove these
unnecessary initializers.

mlx5_device_disable_sriov() currently reads num_vfs from the PCI core.
However when mlx5_device_disable_sriov() is executed, SR-IOV is
already disabled at the PCI level.
Due to this disable_hca() cleanup is not done during SR-IOV disable
flow.
mlx5_sriov_disable()
pci_enable_sriov()
mlx5_device_disable_sriov() <- num_vfs is zero here.
When SR-IOV enablement fails during mlx5_sriov_enable(), HCA's are left
in enabled stage because mlx5_device_disable_sriov() relies on num_vfs
from PCI core.
mlx5_sriov_enable()
mlx5_device_enable_sriov()
pci_enable_sriov() <- Fails
Hence, to overcome above issues,
(a) Read num_vfs before disabling SR-IOV and use it.
(b) Use num_vfs given when enabling sriov in error unwinding path.

Netfilter tables (nftables) implements a software datapath that
comes after tc ingress datapath. The datapath supports offloading
such rules via the flow table offload API.
This API is currently only used by NFT and it doesn't provide the
global priority in regards to tc offload, so we assume offloading such
rules must come after tc. It does provide a flow table priority
parameter, so we need to provide some supported priority range.
For that, split fastpath prio to two, flow table offload and tc offload,
with one dedicated priority chain for flow table offload.
Next patch will re-use the multi chain API to access this chain by
allowing access to this chain by the fdb_sub_namespace.

Tc chains are implemented by creating a chained prio steering type, and
inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each
of those has a list of priorities.
Currently, all namespaces in a prio start at the parent prio level.
But since we can jump from chain (namespace) to another chain in the
same prio, we need the levels for higher chains to be higher as well.
So we created unused prios to account for levels in previous namespaces.
Fix that by accumulating the namespaces levels if we are inside a chained
type prio, and removing the unused prios.

The setup_dpio() function tries to allocate a number of channels equal
to the number of CPUs online. When there are not enough DPCON objects
already probed, the function will return EPROBE_DEFER. When this
happens, the already allocated channels are not freed. This results in
the incapacity of properly probing the next time around.
Fix this by freeing the channels on the error path.

====================
pull-request: can-next 2019-10-07
this is a pull request for net-next/master consisting of 32 patches.
The first patch is by Gustavo A. R. Silva and removes unused code in the
generic CAN infrastructure.
The next three patches target the mcp251x driver. The one by Andy
Shevchenko removes the legacy platform data support from the driver. The
other two are by Timo Schlüßler and reset the device only when needed,
to prevent glitches on the output when GPIO support is added.
I'm contributing two patches fixing checkpatch warnings in the
c_can_platform and peak_canfd driver.
Stephane Grosjean's patch for the peak_canfd driver adds hw timestamps
support in rx skbs.
The next three patches target the xilinx_can driver. One patch by me to
fix checkpatch warnings, one patch by Anssi Hannula to avoid non
requested bus error frames, and a patch by YueHaibing that switches the
driver to devm_platform_ioremap_resource().
Pankaj Sharma contributes two patches for the m_can driver, the first
one adds support for one shot mode, the other support for handling
arbitration errors.
Followed by four patches by YueHaibing, switching the grcan, ifi, rcar,
and sun4i drivers to devm_platform_ioremap_resource()
I'm contributing cleanup patches for the rx-offload helper, while Joakim
Zhang's patch prepares the rx-offload helper for CAN-FD support. The rx
offload users flexcan and ti_hecc are converted accordingly.
The remaining twelve patches target the flexcan driver. First Joakim
Zhang switches the driver to devm_platform_ioremap_resource(). The
remaining eleven patch are by me and clean up the abstract the access of
the iflag1 and iflag2 register both for RX and TX mailboxes. This is a
preparation for the upcoming CAN-FD support.

The sfc driver can drop packets processed with XDP, notably when running
out of buffer space on XDP_TX, or returning an unknown XDP action.
This increments the rx_xdp_bad_drops ethtool counter.
Call trace_xdp_exception everywhere rx_xdp_bad_drops is incremented,
except for fragmented RX packets as the XDP program hasn't run yet.
This allows it to easily be monitored from userspace.
This mirrors the behavior of other drivers.

There is a stray semicolon in an if statement that will cause a dev_err
message to be printed unconditionally. Fix this by removing the stray
semicolon.

updated devlink interface of binary fmsg pair which breaks the output
