6.13-stable review patch. If anyone has any objections, please let me know.

commit 20eb1fae4145bc45717aa8a6d05fcd6a64ed856a upstream.
The bme680_read_temp() function takes a pointer to s16 but we're passing an int pointer to it. This will not work on big endian systems and it also means that the other 16 bits are uninitialized.
Pass an s16 type variable.
