When the third option (list) to ldebugfs_register() is NULL, it's the
same as just calling debugfs_create_dir(). So unwind this and call
debugfs_create_dir() directly.
This ends up saving lots of code as we do not need to do any error
checking of the return value (because it does not matter).
The ldebugfs_register() call will be removed in a later patch when it is
fully removed, right now there are 2 outstanding users of it in the
tree.

It was just calling debugfs_create_file() so unwind things and just call
the real function instead. This ends up saving a number of lines as
there was never any error handling happening anyway, so that all can be

It was only being called in one place, and is an unneeded wrapper

The pmem driver does not honor a forced read-only setting for very long:
$ blockdev --setro /dev/pmem0
$ blockdev --getro /dev/pmem0
1
followed by various commands like these:
$ blockdev --rereadpt /dev/pmem0
or
$ mkfs.ext4 /dev/pmem0
results in this in the kernel serial log:
nd_pmem namespace0.0: region0 read-write, marking pmem0 read-write
with the read-only setting lost:
$ blockdev --getro /dev/pmem0
0
That's from bus.c nvdimm_revalidate_disk(), which always applies the
setting from nd_region (which is initially based on the ACPI NFIT
NVDIMM state flags not_armed bit).
In contrast, commit 20bd1d026aac ("scsi: sd: Keep disk read-only when
re-reading partition") fixed this issue for SCSI devices to preserve
the previous setting if it was set to read-only.
This patch modifies bus.c to preserve any previous read-only setting.
It also eliminates the kernel serial log print except for cases where
read-write is changed to read-only, so it doesn't print read-only to
read-only non-changes.

The previous code was optimistic, accepting the offload of whole action
chain when there was a single known action (drop/redirect). This results
in offloading a rule which should not be offloaded, because its behavior
cannot be reproduced in the hardware.
For example:
$ tc filter add dev eno1 parent ffff: protocol ip \
u32 ht 800: order 1 match tcp src 42 FFFF \
action mirred egress mirror dev enp1s16 pipe \
drop
The controller is unable to mirror the packet to a VF, but still
offloads the rule by dropping the packet.
Change the approach of the function to a pessimistic one, rejecting the
chain when an unknown action is found. This is better suited for future
extensions.
Note that both recognized actions always return TC_ACT_SHOT, therefore
it is safe to ignore actions behind them.

We should use the new method to check if RTC was powered down, which
is more solid. Since we have introduced power control and power status
registers, and we just check if the power status is the default value
(0x96), if yes that means the RTC has been powered down. Meanwhile We
can set the power control register to be one valid value to change
the power status to indicate RTC device is valid now.

clk-gate core will take bit_idx through clk_register_gate
and then do clk_gate_ops by using BIT(bit_idx), but rtc-sun6i
is passing bit_idx as BIT(bit_idx) it becomes BIT(BIT(bit_idx)
which is wrong and eventually external gate clock is not enabling.

that the test can be removed.

The iSER driver reduces max_sectors. For example, if you load the
ib_iser module with max_sectors=1024, you will see that
/sys/class/block/<bdev>/queue/max_hw_sectors_kb is 508. It is an
incorrect value. The expected value is (max_sectors * sector_size) /
1024 = 512.
Reducing of max_sectors can cause performance degradation due to
unnecessary splitting of IO requests.
The number of pages per MR has been fixed here, so there is no longer
any need to reduce max_sectors.

This patch is created to solve the CamelCase issue. The members 'IEs'
and 'IELength' of struct wlan_bssid_ex are being modified to 'ie' and
'ie_length' to solve the issue. And the places where these variables
are referenced inside rtl8188eu driver are also changed.

Something in recent linux-next kernels caused linux/highmem.h to
no longer be included implicitly from o2iblnd_cb.c, causing a build
failure:
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c: In function 'kiblnd_kvaddr_to_page':
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:549:15: error: 'PKMAP_BASE' undeclared (first use in this function); did you mean 'RTM_BASE'?

This adds back an explicit include for the header.

single_open() returns -ENOMEM when malloc failed, so the caller function
rtl_debugfs_open_rw() should not always return 0. In addition, when using
single_open(), we should use single_release() instead of seq_release() in
the file_operations structure to avoid a memory leak.
