In order to support the valid temperature can conver to analog value.
The rockchip thermal driver has not supported the all valid temperature
to convert the analog value. (e.g.: 61C, 62C, 63C....)

For example:
In some cases, we need adjust the trip point.
$cd /sys/class/thermal/thermal_zone*
$echo 68000 > trip_point_0_temp
That will return the max analogic value indicates the invalid before
posting this patch.

So, this patch will optimize the conversion table to support the other
cases.

The temp_to_code function will return 0 when we set the temperature to a
invalid value (e.g. 61C, 62C, 63C....), that's unpractical. This patch
will prevent this case happening. That will return the max analog value to
indicate the temperature is invalid or over table temperature range.

This driver passes struct chip_tsadc_table by value throughout; this is
inefficient, and AFAICT, there is no reason for it. Let's pass pointers
instead.

These error messages don't give much information about what went wrong.
It would be nice, for one, to see what invalid temperature was being
requested when conversion fails. It's also good to return an error when
we can't handle a conversion properly.

While we're at it, fix the grammar too.

This reverts commit 6d31e3ba232ea22458b2f36b6d3f2f9f11bf3fa4.

This causes bootup problems for me both on my laptop and my desktop.
What they have in common is that they have NVMe disks with dm-crypt, but
it's not the same controller, so it's not controller-specific.

Jens does not see it on his machine (also NVMe), so it's presumably
something that triggers just on bootup. Possibly related to dm-crypt
and the fact that I mark my luks volume with "allow-discards" in
/etc/crypttab.

It's 100% repeatable for me, which made it fairly straightforward to
bisect the problem to this commit. Small mercies.

So we don't know what the reason is yet, but the revert is needed to get
things going again.

Pull arm64 updates from Catalin Marinas:

- struct thread_info moved off-stack (also touching
include/linux/thread_info.h and include/linux/restart_block.h)

- cpus_have_cap() reworked to avoid __builtin_constant_p() for static
key use (also touching drivers/irqchip/irq-gic-v3.c)

- uprobes support (currently only for native 64-bit tasks)

- Emulation of kernel Privileged Access Never (PAN) using TTBR0_EL1
switching to a reserved page table

- CPU capacity information passing via DT or sysfs (used by the
scheduler)

- support for systems without FP/SIMD (IOW, kernel avoids touching
these registers; there is no soft-float ABI, nor kernel emulation for
AArch64 FP/SIMD)

- handling of hardware watchpoint with unaligned addresses, varied
lengths and offsets from base

- use of the page table contiguous hint for kernel mappings

- hugetlb fixes for sizes involving the contiguous hint

- remove unnecessary I-cache invalidation in flush_cache_range()

- CNTHCTL_EL2 access fix for CPUs with VHE support (ARMv8.1)

- boot-time checks for writable+executable kernel mappings

- simplify asm/opcodes.h and avoid including the 32-bit ARM counterpart
and make the arm64 kernel headers self-consistent (Xen headers patch
merged separately)

"The main bulk of the s390 patches for the 4.10 merge window:

- Add support for the contiguous memory allocator.

- The recovery for I/O errors in the dasd device driver is improved,
the driver will now remove channel paths that are not working
properly.

- Additional fields are added to /proc/sysinfo, the extended
partition name and the partition UUID.

- New naming for PCI devices with system defined UIDs.

- The last few remaining alloc_bootmem calls are converted to
memblock.

- The thread_info structure is stripped down and moved to the
task_struct. The only field left in thread_info is the flags field.

- Rework of the arch topology code to fix a fake numa issue.

- Refactoring of the atomic primitives and add a new preempt_count
implementation.

- Clocksource steering for the STP sync check offsets.

- The s390 specific headers are changed to make them usable with
CLANG.

- Bug fixes and cleanup"

Commit 4b65a5db3627 ("arm64: Introduce uaccess_{disable,enable}
functionality based on TTBR0_EL1") added conditional user access
enable/disable. Unfortunately, a typo prevents the PAN bit from being
cleared for user access functions.

Restore the PAN functionality by adding the missing '!'.

.inst being largely broken with older binutils, it'd be better not
to emit it altogether when detecting such configuration (as it
leads to all kind of horrors when using alternatives).

Generalize the __emit_inst macro and use it extensively in
asm/sysreg.h, and make it generate a .long when a broken gas is
detected. The disassembly will be crap, but at least we can write
semi-sane code.

Only mark a page as managed when it is released back to the allocator.
This ensures that the managed page count does not get falsely increased
when a VM is running. Correspondingly change it so that pages are
marked as unmanaged after getting them from the allocator.
