If anyone has any objections, please let me know. ------------------ From: Lucy Thrun [ Upstream commit a409c60111e6bb98fcabab2aeaa069daa9434ca0 ] 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.
