The tuning logic at tda8290 relies on agc_stat and adc_sat to be initialized. However, as warned by smatch: drivers/media/tuners/tda8290.c:261 tda8290_set_params() error: uninitialized symbol 'agc_stat'. drivers/media/tuners/tda8290.c:261 tda8290_set_params() error: uninitialized symbol 'adc_sat'. drivers/media/tuners/tda8290.c:262 tda8290_set_params() error: uninitialized symbol 'adc_sat'. That could cause an erratic behavior if PLL is not locked, as the code will only work if !(pll_stat & 0x80) && (adc_sat < 20) So, initialize it to zero, in order to let the code below to be called, with should give more chances to adjust the tuner gain, in order to get a PLL lock.
