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) Tested-by: Stefan Lippers-Hollmann <s.l-h@gmx.de> [nbg6817/ipq8065] Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>

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.
