ALSA: hda/ca0132: Fix buffer overflow in add_tuning_control
Description

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/ca0132: Fix buffer overflow in add_tuning_control 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.
