These structs have holes in them so we end up disclosing a few bytes of
uninitialized stack data.
drivers/misc/xilinx_sdfec.c:305 xsdfec_get_status() warn: check that 'status' doesn't leak information (struct has a hole after 'activity')
drivers/misc/xilinx_sdfec.c:449 xsdfec_get_turbo() warn: check that 'turbo_params' doesn't leak information (struct has a hole after 'scale')
We need to zero out the holes with memset().

When fw fatal error occurs, poll health() first detects and reports on a
fw error. Afterwards, it detects and reports on the fw fatal error
itself.
That can cause a long delay in fw fatal error handling which waits in a
queue for the fw error handling to be finished. The fw error handle will
try asking for fw core dump command while fw in fatal state may not
respond and driver will wait for command timeout.
Changing the flow to detect and handle first fw fatal errors and only if
no fatal error detected look for a fw error to handle.

In commit 6096d91af0b6 ("dm space map metadata: fix occasional leak
of a metadata block on resize"), we refactor the commit logic to a new
function 'apply_bops'. But when that logic was replaced in out() the
return value was not stored. This may lead out() returning a wrong
value to the caller.

When btree_split_beneath() splits a node to two new children, it will
allocate two blocks: left and right. If right block's allocation
failed, the left block will be unlocked and marked dirty. If this
happened, the left block'ss content is zero, because it wasn't
initialized with the btree struct before the attempot to allocate the
right block. Upon return, when flushing the left block to disk, the
validator will fail when check this block. Then a BUG_ON is raised.
Fix this by completely initializing the left block before allocating and
initializing the right block.

All user level and most in-kernel applications submit WQEs
where the SG list entries are all of a single type.
iSER in particular, however, will send us WQEs with mixed SG
types: sge[0] = kernel buffer, sge[1] = PBL region.
Check and set is_kva on each SG entry individually instead of
assuming the first SGE type carries through to the last.
This fixes iSER over siw.

Driver copies FW commands to the HW queue as units of 16 bytes. Some

The SF2 binding does not specify that the CPU port should have
properties mandatory for successfully instantiating a PHYLINK object. As
such, there will be missing properties (including fixed-link) and when
attempting to validate and later configure link modes, we will have an
incorrect set of parameters (interface, speed, duplex).
Simply prevent the CPU port from being configured through PHYLINK since
bcm_sf2_imp_setup() takes care of that already.

[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.
This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.
[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

In certain cases when the probe function fails the error path calls
cpsw_remove_dt() before calling platform_set_drvdata(). This is an
issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the
cpsw_common data and leds to a NULL pointer exception. This patches
fixes it by calling platform_set_drvdata() earlier in the probe.

After _gadget_stop_activity is executed, we can consider the hardware
operation for gadget has finished, and the udc can be stopped and enter
low power mode. So, any later hardware operations (from usb_ep_ops APIs
or usb_gadget_ops APIs) should be considered invalid, any deinitializatons
has been covered at _gadget_stop_activity.
I meet this problem when I plug out usb cable from PC using mass_storage
gadget, my callstack like: vbus interrupt->.vbus_session->
composite_disconnect ->pm_runtime_put_sync(&_gadget->dev),
the composite_disconnect will call fsg_disable, but fsg_disable calls
usb_ep_disable using async way, there are register accesses for
usb_ep_disable. So sometimes, I get system hang due to visit register
without clock, sometimes not.
The Linux Kernel USB maintainer Alan Stern suggests this kinds of solution.

Change the "frontend" dust_remove_block, dust_add_block, and
dust_query_block functions to store the "dust block number", instead
of the sector number corresponding to the "dust block number".
For the "backend" functions dust_map_read and dust_map_write,
right-shift by sect_per_block_shift. This fixes the inability to
emulate failure beyond the first sector of each "dust block" (for
devices with a "dust block size" larger than 512 bytes).

The WRITE_PROTECT bit is always in a "protected mode" on Tegra and
WP-GPIO state need to be used instead. In a case of the GPIO absence,
write-enable should be assumed. External SD is writable once again as
a result of this patch because the offending commit changed behaviour for
the case of a missing WP-GPIO to fall back to WRITE_PROTECT bit-checking,
which is incorrect for Tegra.

The new dma_alloc_contiguous hides if we allocate CMA or regular
pages, and thus fails to retry a ZONE_NORMAL allocation if the CMA
allocation succeeds but isn't addressable. That means we either fail
outright or dip into a small zone that might not succeed either.
