Ansuel Smith 77f4d5c6bb ipq806x: rework ipq806x specific tsense temp driver
Tsense driver for ipq806x have various problem.
- Emit wrong error. On probing of this driver, nvmem driver can be
  not ready and this cause a EDEFER error. Actually this is not an
  error as the kernel will retry to probe the driver after the
  nvmem driver is loaded.
- Use uninitialized value on trigger of critical temp
- Doesn't free allocated memory

Because of this, rework the driver and improve it by removing extra
load of data.

Change the logic of loading data. Use the backup calib data only
when the calib data is not present. As the calibration is only
needed to set the temp offset, we don't really need to read
both calib data and set the offset based only on the backup one.
Also change how the notifier function work. At times when we
output the trigger message, we already have read the temp so
remove the extra read and the wrong uninitialized data that
probably caused a kernel panic for null pointer exception.
(Think we never experience this bug because the router
never reached that temp ever... So just lucky)

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.

Sunshine!
