[ Upstream commit feaf4154d69657af2bf96e6e66cca794f88b1a61 ]
The datasheet lists that "Maximum exposure time is frame
length -25 row periods, where frame length is set by
registers {0x380E, 0x380F}".
However this driver had OV9282_EXPOSURE_OFFSET set to 12
which allowed that restriction to be violated, and would
result in very under-exposed images.
Correct the offset.

The devm_pci_epc_destroy() comment says destroys the EPC device, but it
does not actually do that since devres_destroy() does not call
devm_pci_epc_release(), and it also can not fully undo what the API
devm_pci_epc_create() does, so it is faulty.
Fortunately, the faulty API has not been used by current kernel tree. Use
devres_release() instead of devres_destroy() so the EPC device will be
released.

When too many rdma resources are allocated, rxe needs more time to

can not release the rdma resources correctly.

early_init_dt_alloc_reserved_memory_arch() will free address @base when
suffers memblock_mark_nomap() error, but it still makes kmemleak ignore
the freed address @base via kmemleak_ignore_phys().
That is unnecessary, besides, also causes unnecessary warning messages:
kmemleak_ignore_phys()
-> make_black_object()
-> paint_ptr()
-> kmemleak_warn() // warning message here.
Fix by avoiding kmemleak_ignore_phys() when suffer the error.

Restrict the check for the number of pages handled during an ODP page
fault to direct mkeys.
Perform the check right after handling the page fault and don't
propagate the number of handled pages to callers.
Indirect mkeys and their associated direct mkeys can have different
start addresses. As a result, the calculation of the number of pages to
handle for an indirect mkey may not match the actual page fault
handling done on the direct mkey.
For example:
A 4K sized page fault on a KSM mkey that has a start address that is not
aligned to a page will result a calculation that assumes the number of
pages required to handle are 2.
While the underlying MTT might be aligned will require fetching only a
single page.
Thus, do the calculation and compare number of pages handled only per
direct mkey.

As of_find_node_by_name() release the reference of the argument device
node, tegra_emc_find_node_by_ram_code() releases some device nodes while
still in use, resulting in possible UAFs. According to the bindings and
the in-tree DTS files, the "emc-tables" node is always device's child
node with the property "nvidia,use-ram-code", and the "lpddr2" node is a
child of the "emc-tables" node. Thus utilize the
for_each_child_of_node() macro and of_get_child_by_name() instead of
of_find_node_by_name() to simplify the code.
This bug was found by an experimental verification tool that I am
developing.
