The `res` variable is already a `struct resource *`, don't take the address of it.

If the shared memory object is larger than the DRM object that it backs,
we can overrun the page array. Limit the number of pages we install

One of the ways of looking up GPIO devices is using their fwnode.
Provide a helper for that to avoid every user implementing their

The functions drm_framebuffer_plane_{width,height} and
fb_plane_{width,height} do exactly the same job of its
equivalents drm_format_info_plane_{width,height} from drm_fourcc.
The only reason to have these functions on drm_framebuffer
would be if they would added a abstraction layer to call it just
passing a drm_framebuffer pointer and the desired plane index,
which is not the case, where these functions actually implements
just part of it. In the actual implementation, every call to both
drm_framebuffer_plane_{width,height} and fb_plane_{width,height} should
pass some drm_framebuffer attribute, which is the same as calling the
drm_format_info_plane_{width,height} functions.
The drm_format_info_pane_{width,height} functions are much more
consistent in both its implementation and its location on code. The
kind of calculation that they do is intrinsically derivated from the
drm_format_info struct and has not to do with drm_framebuffer, except
by the potential motivation described above, which is still not a good
justification to have drm_framebuffer functions to calculate it.
So, replace each drm_framebuffer_plane_{width,height} and
fb_plane_{width,height} call to drm_format_info_plane_{width,height}
and remove them.

Rename the fbdev mmap helper fb_pgprotect() to pgprot_framebuffer().
The helper sets VMA page-access flags for framebuffers in device I/O
memory.
Also clean up the helper's parameters and return value. Instead of
the VMA instance, pass the individial parameters separately: existing
page-access flags, the VMAs start and end addresses and the offset
in the underlying device memory rsp file. Return the new page-access
flags. These changes align pgprot_framebuffer() with other pgprot_()
functions.

The brcmstb-avs-cpufreq driver is considered a legacy driver and since
2018, ARCH_BRCMSTB systems have been using scmi-cpufreq. As a matter of
fact, when SCMI is in use, brcmstb-avs-cpufreq is unusable since the
SCMI firmware takes over, this can result in various problems, including
external synchronous aborts.
Express those constraints such that the driver is not enabled by default
when SCMI CPU frequency scaling is in use.

Rework network interface logic. Before this change, the code flow was:
1. Disable interrupt
2. Try to schedule a NAPI
3. Check if it was possible (NAPI is not already scheduled)
4. emit BUG() if we receive interrupt while a NAPI is scheduled
If some application busy poll or set gro_flush_timeout low enough, it's
possible to reach the BUG() condition. Given that the condition may
happen and it wouldn't be a bug, rework the logic to permit such case
and prevent stall with interrupt never enabled again.
Disable the interrupt only if the NAPI can be scheduled (aka it's not
already scheduled) and drop the printk and BUG() call. With these
change, in the event of a NAPI already scheduled, the interrupt is
simply ignored with nothing done.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
bfa_ioc_get_adapter_manufacturer() simply copies a string literal into
`manufacturer`.
Another implementation of bfa_ioc_get_adapter_manufacturer() from
drivers/scsi/bfa/bfa_ioc.c uses memset + strscpy:
| void
| bfa_ioc_get_adapter_manufacturer(struct bfa_ioc_s *ioc, char *manufacturer)
| {
| memset((void *)manufacturer, 0, BFA_ADAPTER_MFG_NAME_LEN);
| strscpy(manufacturer, BFA_MFG_NAME, BFA_ADAPTER_MFG_NAME_LEN);
| }
Let's use `strscpy_pad` to eliminate some redundant work while still
NUL-terminating and NUL-padding the destination buffer.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect `irqname` to be NUL-terminated based on its use with
of_irq_get_byname() -> of_property_match_string() wherein it is used
with a format string and a `strcmp`:
| pr_debug("comparing %s with %s\n", string, p);
| if (strcmp(string, p) == 0)
| return i; /* Found it; return index */
NUL-padding is not required as is evident by other assignments to
`irqname` which do not NUL-pad:
| if (port->flags & MVPP2_F_DT_COMPAT)
| snprintf(irqname, sizeof(irqname), "tx-cpu%d", i);
| else
| snprintf(irqname, sizeof(irqname), "hif%d", i);
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We can see that linfo->lmac_type is expected to be NUL-terminated based
on the `... - 1`'s present in the current code. Presumably making room
for a NUL-byte at the end of the buffer.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
Let's also prefer the more idiomatic strscpy usage of (dest, src,
sizeof(dest)) rather than (dest, src, SOME_LEN).

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

We enable a bunch more compiler warnings than the kernel
defaults. However, they've drifted to become a unique set of warnings,
and have increasingly fallen behind from the W=1 set.
Align with the W=1 warnings from scripts/Makefile.extrawarn for clarity,
by copy-pasting them with s/KBUILD_CFLAGS/subdir-ccflags-y/ to make it
easier to compare in the future.
Some of the -Wextra warnings do need to be disabled, just like in
Makefile.extrawarn, but take care to not disable them for W=2 or W=3
builds, depending on the warning.

Currently, with MFD/pin assignment D, the driver clears the pipe reset bit
of lane 1 which is not owned by display. This causes the display
to block S0iX.
By not clearing this bit for lane 1 and keeping whatever default, S0ix
started to work. This is already what the driver does at the end
of the phy lane reset sequence (Step#8)

When the vhci device is opened in the two-step way, i.e.: open device
then write a vendor packet with requested controller type, the device
shall respond with a vendor packet which includes HCI index of created
interface.
When the virtual HCI is created, the host sends a reset request to the
controller. This request is processed by the vhci_send_frame() function.
However, this request is send by a different thread, so it might happen
that this HCI request will be received before the vendor response is
queued in the read queue. This results in the HCI vendor response and
HCI reset request inversion in the read queue which leads to improper
behavior of btvirt:
> dmesg
[1754256.640122] Bluetooth: MGMT ver 1.22
[1754263.023806] Bluetooth: MGMT ver 1.22
[1754265.043775] Bluetooth: hci1: Opcode 0x c03 failed: -110
In order to synchronize vhci two-step open/setup process with virtual
HCI initialization, this patch adds internal lock when queuing data in
the vhci_send_frame() function.

Incoming connection might be either 'normal' NVMe-TCP connections
starting with icreq or TLS handshakes. To ensure that 'normal'
connections can still be handled we need to peek the first packet
and only start TLS handshake if it's not an icreq.
With that we can lift the restriction to always set TREQ to
'required' when TLS1.3 is enabled.
