When calling debugfs functions, there is no need to ever check the
return value. This driver was saving the debugfs file away to be
removed at a later time. However, the 80211 core would delete the whole
directory that the debugfs files are created in, after it asks the
driver to do the deletion, so just rely on the 80211 core to do all of
the cleanup for us, making us not need to keep a pointer to the dentries
around at all.
This cleans up the structure of the driver data a bit and makes the code
a tiny bit smaller.

Unlike IPv4, the kernel does not consolidate IPv6 nexthop groups. To
avoid exhausting the device's adjacency table - where nexthops are
stored - the driver does this consolidation instead.
Each nexthop group is hashed by XOR-ing the interface indexes of all the
member nexthop devices. However, the ifindex itself is not hashed, which
can result in identical keys used for different groups and finally an
-EBUSY error from rhashtable due to too long objects list.
Improve the situation by hashing the ifindex itself.

The mlx4_dev_cap and mlx4_init_hca_param are really too large
to be put on the kernel stack, as shown by this clang warning:
drivers/net/ethernet/mellanox/mlx4/main.c:3304:12: error: stack frame size of 1088 bytes in function 'mlx4_load_one' [-Werror,-Wframe-larger-than=]
With gcc, the problem is the same, but it does not warn because
it does not inline this function, and therefore stays just below
the warning limit, while clang is just above it.
Use kzalloc for dynamic allocation instead of putting them
on stack. This gets the combined stack frame down to 424 bytes.

pull-request: can-next 2019-07-24
this is a pull request for net-next/master consisting of 26 patches.
The first two patches are by me. One adds missing files of the CAN
subsystem to the MAINTAINERS file, while the other sorts the
Makefile/Kconfig of the sja1000 drivers sub directory. In the next patch
Ji-Ze Hong (Peter Hong) provides a driver for the "Fintek PCIE to 2 CAN"
controller, based on the the sja1000 IP core.
Gustavo A. R. Silva's patch for the kvaser_usb driver introduces the use
of struct_size() instead of open coding it. Henning Colliander's patch
adds a driver for the "Kvaser PCIEcan" devices.
Another patch by Gustavo A. R. Silva marks expected switch fall-throughs
properly.
Dan Murphy provides 5 patches for the m_can. After cleanups a framework
is introduced so that the driver can be used from memory mapped IO as
well as SPI attached devices. Finally he adds a driver for the tcan4x5x
which uses this framework.
A series of 5 patches by Appana Durga Kedareswara rao for the xilinx_can
driver, first clean up,then add support for CANFD. Colin Ian King
contributes another cleanup for the xilinx_can driver.
Robert P. J. Day's patch corrects the brief history of the CAN protocol
given in the Kconfig menu entry.
2 patches by Dong Aisheng for the flexcan driver provide PE clock source
select support and dt-bindings description.
2 patches by Sean Nyekjaer for the flexcan driver provide add CAN
wakeup-source property and dt-bindings description.
Jeroen Hofstee's patch converts the ti_hecc driver to make use of the
rx-offload helper fixing a number of outstanding bugs.
The first patch of Oliver Hartkopp removes the now obsolete empty
ioctl() handler for the CAN protocols. The second patch adds SPDX

As already mentioned in [1] and included in [2], there is an off by one
issue since the high bank is already enabled when the _next_ mailbox to
be read has index 12, so the mailbox being read was 13. The message can
therefore go into mailbox 31 and the driver will be repolled until the
mailbox 12 eventually receives a msg. Or the message might end up in the
12th mailbox, but then it would become disabled after reading it and only
be enabled again in the next "round" after mailbox 13 was read, which can
cause out of order messages, since the lower priority mailboxes can
accept messages in the meantime.
As mentioned in [3] there is a hardware race condition when changing the
CANME register while messages are being received. Even when including a
busy poll on reception, like in [2] there are still overflows and out of
order messages at times, but less then without the busy loop polling.
Unlike what the patch suggests, the polling time is not in the microsecond
range, but takes as long as a current CAN bus reception needs to finish,
so typically more in the fraction of millisecond range. Since the timeout
is in jiffies it won't timeout.
Even with these additional fixes the driver is still not able to provide a
proper FIFO which doesn't drop packages. So change the driver to use
rx-offload and base order on timestamp instead of message box numbers. As
a side affect, this also fixes [4] and [5].
Before this change messages with a single byte counter were dropped /
received out of order at a bitrate of 250kbit/s on an am3517. With this
patch that no longer occurs up to and including 1Mbit/s.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = alloc(sizeof(struct foo) + count * sizeof(void *));
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = alloc(struct_size(instance, entry, count));
