devicetree is not available. Update sdpm driver probe logic to
proceed with the available clocks.

We are seeing M_TX_FIFO_WATERMARK_EN timeout during
console_write and M_CMD_OVERRUN is getting set which
indicates a new command is initialized by SW, before
the previous one has been completed. There is some data
in TX FIFO and before UART transaction is finished,
console_write() is called again without clearing the
m_irq_status.
During the next console_write if tx geni is
active and previous console_write was incomplete,
ensure the m_irq_status is cleared by calling
msm_geni_serial_poll_tx_done before triggering further
write operations.

The sysfs apis duplicate the input string with kstrdup() and use strsep()
to parse the copied string. However since calls to strsep() can modify
the string pointer, it is incorrect to use the same pointer to free the
copied string. Instead, save the original location of the string so
that it can be properly freed at the end.

For out-of-tree builds, this script invokes cpio twice to copy header
files from the srctree and subsequently from the objtree. According to a
comment in the script, there might be situations in which certain files
already exist in the destination directory when header files are copied
from the objtree:
"The second CPIO can complain if files already exist which can happen
with out of tree builds having stale headers in srctree. Just silence
CPIO for now."
GNU cpio might simply print a warning like "newer or same age version
exists", but toybox cpio exits with a non-zero exit code unless the
command line option "-u" is specified.
To improve compatibility with toybox cpio, add the command line option
"-u" to unconditionally replace existing files in the destination
directory.

between the ioctl and bind operation on the heap for simplicity.

The config buffer is stack variable and it consumes

Use heap memory for config buffer variable and

Currently driver supports sampling rates starting from 100ms to
2 seconds. Extend it to support sampling rates down to 1ms. Upto
50ms the granularity of sampling period supported is in multiples of 1.
Beyond 50ms it is in multiples of 50. i.e User space can set sampling
periods from 1ms to 50ms in steps of 1 beyond that in steps of 50.

UAF scenario may occur in clients with EL1 privileges for
iova mappings when we miss to check the return value of
arm_lpae_init_pte which may lead to an PTE be counted as
it was set even if it was already existing. This can cause a
dangling IOMMU PTE to be left mapped pointing to a
freed object and cause UAF in the client if the dangling PTE
is accessed after a failed unmap operation.

Currently, when a page is allocated from a dma-buf pool,
the page owner shows the owner to be the refill worker thread
which has created the pool. It is incorrect, since there can be
many clients who have allocated pages from the pool and there is
no way to know the owner of those pages. Set page owner while
allocating from pool to show correct owner.
