hwmon: (max1111) Fix race condition causing NULL pointer exception
commit d3f684f2820a7f42acef68bea6622d9032127fb2 upstream.
spi_sync call uses its spi_message parameter to keep completion information,
using a drvdata structure is not thread-safe. Use a mutex to prevent
multiple access to shared driver data.
