The kernel WARNs and then crashes today if wm8994_device_init() fails
after calling devm_regulator_bulk_get().
That happens because there are multiple devices involved here and the
order in which managed resources are freed isn't correct.
The regulators are added as children of wm8994->dev. Whereas,
devm_regulator_bulk_get() receives wm8994->dev as the device, though it
gets the same regulators which were added as children of wm8994->dev
earlier.
During failures, the children are removed first and the core eventually
calls regulator_unregister() for them. As regulator_put() was never done
for them (opposite of devm_regulator_bulk_get()), the kernel WARNs at
WARN_ON(rdev->open_count);
And eventually it crashes from debugfs_remove_recursive().

When loading the TX fifo to receive bytes on the I2C bus, we incorrectly
count the number of bytes:
rx_limit = dev->rx_fifo_depth - dw_readl(dev, DW_IC_RXFLR);
while (buf_len > 0 && tx_limit > 0 && rx_limit > 0) {
if (rx_limit - dev->rx_outstanding <= 0)
break;
rx_limit--;
dev->rx_outstanding++;
}
DW_IC_RXFLR indicates how many bytes are available to be read in the
FIFO, dev->rx_fifo_depth is the FIFO size, and dev->rx_outstanding is
the number of bytes that we've requested to be read so far, but which
have not been read.
Firstly, increasing dev->rx_outstanding and decreasing rx_limit and then
comparing them results in each byte consuming "two" bytes in this
tracking, so this is obviously wrong.
Secondly, the number of bytes that _could_ be received into the FIFO at
any time is the number of bytes we have so far requested but not yet
read from the FIFO - in other words dev->rx_outstanding.
So, in order to request enough bytes to fill the RX FIFO, we need to
request dev->rx_fifo_depth - dev->rx_outstanding bytes.
Modifying the code thusly results in us reaching the maximum number of
bytes outstanding each time we queue more "receive" operations, provided
the transfer allows that to happen.

Tune dsi frame rate by pixel clock, dsi add some extra signal (i.e.
Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP
mode, those signals will cause h-time larger than normal and reduce FPS.
So need to multiply a coefficient to offset the extra signal's effect.

The commit 8dfbcc4351a0 ("[media] xc2028: avoid use after free") tried
to address the reported use-after-free by clearing the reference.
However, it's clearing the wrong pointer; it sets NULL to
priv->ctrl.fname, but it's anyway overwritten by the next line
memcpy(&priv->ctrl, p, sizeof(priv->ctrl)).
OTOH, the actual code accessing the freed string is the strcmp() call
with priv->fname:
if (!firmware_name[0] && p->fname &&
priv->fname && strcmp(p->fname, priv->fname))
free_firmware(priv);
where priv->fname points to the previous file name, and this was
already freed by kfree().
For fixing the bug properly, this patch does the following:
- Keep the copy of firmware file name in only priv->fname,
priv->ctrl.fname isn't changed;
- The allocation is done only when the firmware gets loaded;
- The kfree() is called in free_firmware() commonly

When PCIe port PM is not enabled (system BIOS is pre-2015 or the
pcie_port_pm=off parameter is set), legacy ATPX PM should still be
marked as supported. Otherwise the GPU can fail to power on after
runtime suspend. This affected a Dell Inspiron 5548.
Ideally the BIOS date in the PCI core is lowered to 2013 (the first year
where hybrid graphics platforms using power resources was introduced),
but that seems more risky at this point and would not solve the
pcie_port_pm=off issue.

When user tried to read some fields like hysteresis from IIO sysfs on some
systems, it fails. The reason is that this field is a byte field and caller
of sensor_hub_get_feature() passes a buffer of 4 bytes. Here the function
sensor_hub_get_feature() copies the single byte from the report to the
caller buffer and returns "1" as the number of bytes copied. So caller
can use the return value.
But this is done by multiple callers, so if we just change the
sensor_hub_get_feature so that caller buffer is initialized with 0s
then we don't to change all functions.

Pull thermal management fix from Zhang Rui:
"We only have one urgent fix this time.
Commit 3105f234e0ab ("thermal/powerclamp: correct cpu support check"),
which is shipped in 4.9-rc3, fixed a problem introduced by commit
b721ca0d1927 ("thermal/powerclamp: remove cpu whitelist").
But unfortunately, it broke intel_powerclamp driver module auto-
loading at the same time. Thus we need this change to add back module
auto-loading for 4.9"

One prevents timeouts on mpt3sas when trying to use the secure erase

a regression in a prior fix which causes all commands to abort during
PCI extended error recovery, which is incorrect because PCI EEH is

While testing HDMI with Xorg on the Juno board, I find that when Xorg
starts up or shuts down, the display is shifted significantly to the
right and wrapped in the active region. (No sync bars are visible.)
The timings are correct, it behaves as if the start address has been
shifted many pixels _into_ the framebuffer.
This occurs whenever the display mode size is changed - using xrandr
in Xorg shows that changing the resolution triggers the problem
almost every time, but changing the refresh rate does not.
Using devmem2 to disable and re-enable the HDLCD resolves the issue,
and repeated disable/enable cycles do not make the issue re-appear.
Further debugging shows that we try to update the controller
configuration while enabled.
Alwys ensure that the HDLCD is disabled prior to updating the
controller timings, and use drm_crtc_vblank_off()/drm_crtc_vblank_on()
so that DRM knows whether it can expect vblank interrupts.

The WDAT watchdog driver uses functionality provided by the watchdog timer
core but it did not select it explicitly. This results following linker
error when only WDAT_WDT is enabled in Kconfig:
drivers/built-in.o: In function `wdat_wdt_probe':
drivers/watchdog/wdat_wdt.c:444: undefined reference to `devm_watchdog_register_device'
Fix this by explicitly selecting WATCHDOG_CORE when WDAT watchdog driver is
enabled.

7) If a driver does a napi_hash_del() explicitily and not via
netif_napi_del(), it must perform RCU synchronization as needed. Fix
this in virtio-net and bnxt drivers, from Eric Dumazet.

also doing neif_napi_del() in the same code path. Remove such calls
from be2net and cxgb4 drivers, also from Eric Dumazet.

When dma->start is failed,then it has to fall back to PIO mode
for current transfer.
But Host controller was already set to bits relevant to DMA operation.
If needs to use the PIO mode, Host controller has to stop the DMA
operation. (It's more stable than now.)
When it occurred error, it's not running any request.
