ALSA: hda/ca0132: Fix buffer overflow in add_tuning_control

Browse source

The 'sprintf' call in 'add_tuning_control' may exceed the 44-byte
buffer if either string argument is too long. This triggers a compiler
warning.
Replaced 'sprintf' with 'snprintf' to limit string lengths to prevent
overflow.
