| | | | | | | | | | | | | | | | | | | | adc_tm5_register_tzd() registers the thermal zone sensors for all channels of the thermal monitor. If the registration of one channel fails the function skips the processing of the remaining channels and returns an error, which results in _probe() being aborted. One of the reasons the registration could fail is that none of the thermal zones is using the channel/sensor, which hardly is a critical error (if it is an error at all). If this case is detected emit a warning and continue with processing the remaining channels.

The following has been explained in the cover letter. I am including this here so that this remains in the commit message as well. LMh is a hardware infrastructure on some Qualcomm SoCs that can enforce temperature and current limits as programmed by software for certain IPs like CPU. On many newer LMh is configured by firmware/TZ and no programming is needed from the kernel side. But on certain SoCs like sdm845 the firmware does not do a complete programming of the h/w. On such soc's kernel software has to explicitly set up the temperature limits and turn on various monitoring and enforcing algorithms on the hardware.

* thermal: qcom: tsens.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva2020-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
