The sparse tool complains as follows:
drivers/soc/ti/knav_qmss_acc.c:453:23: warning:
symbol 'knav_acc_range_ops' was not declared. Should it be static?
'knav_acc_range_ops' is not used outside of knav_qmss_acc.c,
so marks it static.

For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:

If both the HTTP and HTTPS versions
return 200 OK and serve the same content:

The drivers/memory directory with memory controller drivers, over the
last days grew in numbers but lacked any coordinated care. The generic
part (device tree helpers) were pulled in through various trees,
depending on driver needs.
The patchset is a first try to improve code quality of memory controller
drivers. Mostly these are non-intrusive fixes for GCC, checkpatch or
sparse warnings. This also fixes missing SPDX tags or improves generic
code quality (whitespace, const correctness).
Last commit appoints also Krzysztof Kozlowski as a maintainer.

Check for regmap_read() return code before using the read value in
following write in exynos5_switch_timing_regs(). Pass reading error
code to the callers.
This does not introduce proper error handling for such failed reads (and
obviously regmap_write() error is still ignored) because the driver
ignored this in all places. Therefor it only fixes reported issue while
matching current driver coding style:

Add a simple custom voltage regulator coupler for Exynos5800 SoCs, which
require coupling between "vdd_arm" and "vdd_int" regulators. This coupler
ensures that the voltage values don't go below the bootloader-selected
operation point during the boot process until the clients set their
constraints. It is achieved by assuming minimal voltage value equal to
the current value if no constraints are set. This also ensures proper
voltage balancing if any of the client driver is missing.
The balancing code comes from the regulator/core.c with the additional
logic for handling regulators without client constraints applied added.

pdev struct doesn't exits for the devices whose status are disabled
from DT node, in such cases NULL is returned from 'of_find_device_by_node'
Later when we try to get drvdata from pdev struct NULL pointer dereference
is triggered.
Add a NULL check for return values to fix the issue.
We were hitting this issue when one of QUP is disabled.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

The firmware on Turris MOX secure processor offers signing messages
with ECDSA private key stored in protected OTP memory.
The optimal solution would be to register an akcipher provider via
kernel's crypto API, but crypto API does not yet support accessing
akcipher API from userspace (and probably won't for some time, see
https://www.spinics.net/lists/linux-crypto/msg38388.html).
At first I tried to put this via standard sysfs API, but the way I
designed it is not compatible with sysfs's standard "one file per
attribute".
This patch therefore adds support for accessing this signature
generation mechanism via debugfs. Since CZ.NIC's Turris MOX is the only
user of this module, the potential future change to akcipher API should
not cause problems, since we can just change our userspace software then.
