Vasileios Amoiridis 77641e5a47 iio: chemical: bme680: Fix read/write ops to device by adding mutexes
Add mutexes in the {read/write}_raw() functions of the device to guard the
read/write of data from/to the device. This is necessary because for any
operation other than temperature, multiple reads need to take place from
the device. Even though regmap has a locking by itself, it won't protect us
from multiple applications trying to read at the same time temperature and
pressure since the pressure reading includes an internal temperature
reading and there is nothing to ensure that this temperature+pressure
reading will happen sequentially without any other operation interfering
in the meantime.
