If anyone has any objections, please let me know. ------------------ From: Mauro Carvalho Chehab commit 2d861977e7314f00bf27d0db17c11ff5e85e609a upstream. The loop at stb0899_search_carrier() starts with a random value for cfr, as reported by Coverity. Initialize it to zero, just like stb0899_dvbs_algo() to ensure that carrier search won't bail out.
