Limit the output of humidity compensation to the range between 0 and 100
percent.
Depending on the calibration parameters of the individual sensor it
happens, that a humidity above 100 percent or below 0 percent is
calculated, which don't make sense in terms of relative humidity.
Add a clamp to the compensation formula as described in the datasheet of
the sensor in chapter 4.2.3.
Although this clamp is documented, it was never in the driver of the
kernel.
It depends on the circumstances (calibration parameters, temperature,
humidity) if one can see a value above 100 percent without the clamp.
The writer of this patch was working with this type of sensor without
noting this error. So it seems to be a rare event when this bug occures.

When resizing a BAR, pci_reassign_bridge_resources() is invoked to bring
the bridge windows of parent bridges in line with the new BAR assignment.
This assumes the device whose BAR is being resized lives on a subordinate
bus, but this is not necessarily the case. A device may live on the root
bus, in which case dev->bus->self is NULL, and passing a NULL pci_dev
pointer to pci_reassign_bridge_resources() will cause it to crash.
So let's make the call to pci_reassign_bridge_resources() conditional on
whether dev->bus->self is non-NULL in the first place.

Free the sgtables allocated by scsi_init_io() in case scsi_setup_fs_cmnd()
fails.
Technically scsi_setup_scsi_cmnd() does not suffer from this problem as it
can only fail if scsi_init_io() fails, so it does not have sgtables
allocated. But to maintain symmetry and as a measure of defensive
programming, free the sgtables on scsi_setup_scsi_cmnd() failure as well.
scsi_mq_free_sgtables() has safeguards against double-freeing of memory so
this is safe to do.
While we're at it, rename scsi_mq_free_sgtables() to scsi_free_sgtables().

davinci_mcasp_get_dma_type() invokes dma_request_chan(), which returns a
reference of the specified dma_chan object to "chan" with increased
refcnt.
When davinci_mcasp_get_dma_type() returns, local variable "chan" becomes
invalid, so the refcount should be decreased to keep refcount balanced.
The reference counting issue happens in one exception handling path of
davinci_mcasp_get_dma_type(). When chan device is NULL, the function
forgets to decrease the refcnt increased by dma_request_chan(), causing
a refcnt leak.

[ Upstream commit f47ab3c2f5 ]
During the process of debugging a processor derived from the msm8916 which
we found the new processor was not starting one of its PLLs.
After tracing the addresses and writes that downstream was doing and
comparing to upstream it became obvious that we were writing to a different
register location than downstream when trying to configure the PLL.
This error is also present in upstream msm8916.
As an example clk-pll.c::clk_pll_recalc_rate wants to write to
pll->config_reg updating the bit-field POST_DIV_RATIO. That bit-field is
defined in PLL_USER_CTL not in PLL_CONFIG_CTL. Taking the BIMC PLL as an
example
lm80-p0436-13_c_qc_snapdragon_410_processor_hrd.pdf
0x01823010 GCC_BIMC_PLL_USER_CTL
0x01823014 GCC_BIMC_PLL_CONFIG_CTL
This pattern is repeated for gpll0, gpll1, gpll2 and bimc_pll.
This error is likely not apparent since the bootloader will already have
initialized these PLLs.
This patch corrects the location of config_reg from PLL_CONFIG_CTL to
PLL_USER_CTL for all relevant PLLs on msm8916.

But at the time the ida_simple_get() call is made, the notifyids
field in the remoteproc structure has not been initialized.
I'm not actually sure this case causes an observable problem, but
it's incorrect. Fix this by initializing the notifyids field before

Since commit 03db8b583d ("perf tools: Fix
maps__find_symbol_by_name()") introduced map address range check in
maps__find_symbol_by_name(), we can not get "_etext" from kernel map
because _etext is placed on the edge of the kernel .text section (=
kernel map in perf.)
To fix this issue, this checks the address correctness by map address
range information (map->start and map->end) instead of using _etext
address.
This can cause an error if the target inlined function is embedded in
both __init function and normal function.
For exaample, request_resource() is a normal function but also embedded
in __init reserve_setup(). In this case, the probe point in
reserve_setup() must be skipped.
However, without this fix, it failes to setup all probe points:

commit 75e9a330a9 upstream.
nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.
There is no real Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense even if this commit is not
introducing any bug.

commit c5be12e459 upstream.
Not sure nand_cleanup() is the right function to call here but in any
case it is not nand_release(). Indeed, even a comment says that
calling nand_release() is a bit of a hack as there is no MTD device to
unregister. So switch to nand_cleanup() for now and drop this
comment.

commit 1d5d08ee9b upstream.
During ONFI detection, the CRC derived from the parameter page and the
CRC supposed to be at the end of the parameter page are compared. If
they do not match, the second then the third copies of the page are
tried.
The current implementation compares the newly derived CRC with the CRC
contained in the first page only. So if this particular CRC area has
been corrupted, then the detection will fail for a wrong reason.
Fix this issue by checking the derived CRC against the right one.

commit 24c5efe41c upstream.
gss_mech_register() calls svcauth_gss_register_pseudoflavor() for each
flavour, but gss_mech_unregister() does not call auth_domain_put().
This is unbalanced and makes it impossible to reload the module.
Change svcauth_gss_register_pseudoflavor() to return the registered
auth_domain, and save it for later release.
