mtd: rawnand: denali: Use managed device resources
All of the resources used by this driver has managed interfaces, so use
them. Otherwise we will get the following splat:

| In the Linux kernel, the following vulnerability has been resolved:
cpufreq: governor: Use kobject release() method to free dbs_data
The struct dbs_data embeds a struct gov_attr_set and
the struct gov_attr_set embeds a kobject. Since every kobject must have
a release() method and we can't use kfree() to free it directly,
so introduce cpufreq_dbs_data_release() to release the dbs_data via
the kobject::release() method. This fixes the calltrace like below:

| In the Linux kernel, the following vulnerability has been resolved:
ath11k: Change max no of active probe SSID and BSSID to fw capability
The maximum number of SSIDs in a for active probe requests is currently
reported as 16 (WLAN_SCAN_PARAMS_MAX_SSID) when registering the driver.
The scan_req_params structure only has the capacity to hold 10 SSIDs.
This leads to a buffer overflow which can be triggered from
wpa_supplicant in userspace. When copying the SSIDs into the
scan_req_params structure in the ath11k_mac_op_hw_scan route, it can
overwrite the extraie pointer.
Firmware supports 16 ssid * 4 bssid, for each ssid 4 bssid combo probe
request will be sent, so totally 64 probe requests supported. So
set both max ssid and bssid to 16 and 4 respectively. Remove the
redundant macros of ssid and bssid.

| A vulnerability exists in F5OS-A software that allows a highly privileged authenticated attacker to access sensitive FIPS hardware security module (HSM) information on F5 rSeries systems. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: clk-rcg2: Update logic to calculate D value for RCG
The display pixel clock has a requirement on certain newer platforms to
support M/N as (2/3) and the final D value calculated results in
underflow errors.
As the current implementation does not check for D value is within
the accepted range for a given M & N value. Update the logic to
calculate the final D value based on the range. |
| In the Linux kernel, the following vulnerability has been resolved:
drivers: ethernet: cpsw: fix panic when interrupt coaleceing is set via ethtool
cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync
when successful.
pm_runtime_get_sync returns -error code on failure and 0 on successful
resume but also 1 when the device is already active. So the common case
for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls
to pm_runtime_put in the call-chain so that pm_runtime_put is called
one too many times and as result leaving the cpsw dev behind suspended.
The suspended cpsw dev leads to an access violation later on by
different parts of the cpsw driver.
Fix this by calling the return-friendly pm_runtime_resume_and_get
function. |

As Andrew correctly mentioned previously[0], the following call
ladder happens:
ice_misc_intr() <- hardirq
ice_send_event_to_aux()
device_lock()
mutex_lock()
might_sleep()
might_resched() <- oops
Add a new PF state bit which indicates that an aux critical error
occurred and serve it in ice_service_task() in process context.
The new ice_pf::oicr_err_reg is read-write in both hardirq and
process contexts, but only 3 bits of non-critical data probably
aren't worth explicit synchronizing (and they're even in the same
byte [31:24]).

The assumption when these were relaxed seems to be that device memory
would be mapped non reordering, and that other constructs
(spinlocks/etc) would provide the barriers to assure that packet data
and in memory rings/queues were ordered with respect to device
register reads/writes. This itself seems a bit sketchy, but the real
problem with GCC12 is that it is moving the actual reads/writes around
at will as though they were independent operations when in truth they
are not, but the compiler can't know that. When looking at the
assembly dumps for many of these routines its possible to see very
clean, but not strictly in program order operations occurring as the
compiler would be free to do if these weren't actually register
reads/write operations.
Its possible to suppress the timeout with a liberal bit of dma_mb()'s
sprinkled around but the device still seems unable to reliably
send/receive data. A better plan is to use the safer readl/writel
everywhere.
Since this partially reverts an older commit, which notes the use of
the relaxed variants for performance reasons. I would suggest that
any performance problems

igc_ethtool_set_ringparam() copies the igc_ring structure but neglects to
reset the xdp_rxq_info member before calling igc_setup_rx_resources().
This in turn calls xdp_rxq_info_reg() with an already registered xdp_rxq_info.
Make sure to unregister the xdp_rxq_info structure first in
igc_setup_rx_resources. |

net: asix: add proper error handling of usb read errors
Syzbot once again hit uninit value in asix driver. The problem still the
same -- asix_read_cmd() reads less bytes, than was requested by caller.
Since all read requests are performed via asix_read_cmd() let's catch
usb related error there and add __must_check notation to be sure all
callers actually check return value.
So, this patch adds sanity check inside asix_read_cmd(), that simply
checks if bytes read are not less, than was requested and adds missing
error handling of asix_read_cmd() all across the driver code. |

| In the Linux kernel, the following vulnerability has been resolved:
ptp: unregister virtual clocks when unregistering physical clock.
When unregistering a physical clock which has some virtual clocks,
unregister the virtual clocks with it.
This fixes the following oops, which can be triggered by unloading
a driver providing a PTP clock when it has enabled virtual clocks:

| In the Linux kernel, the following vulnerability has been resolved:
media: stk1160: If start stream fails, return buffers with VB2_BUF_STATE_QUEUED
If the callback 'start_streaming' fails, then all
queued buffers in the driver should be returned with
state 'VB2_BUF_STATE_QUEUED'. Currently, they are
returned with 'VB2_BUF_STATE_ERROR' which is wrong.
Fix this. This also fixes the warning:
