Re: [TESTING] - NAND OMGB (1.2.3)

Found Division by zero in kernel.

htc_rhod_batt_corr() in file htc_battery_smem.c

Code:
    BATT("htc_get_batt_info 888\n");
        /* TODO: temp algo is not ok..if someone have the timte -> must look into the driver */
    buffer->batt_tempRAW = ( buffer->batt_tempRAW * 5200 ) / htc_adc_range;
    BATT("htc_get_batt_info 999\n");
    av_index = ( buffer->batt_tempRAW * 18 ) / ( 2600 - buffer->batt_tempRAW );
    BATT("htc_get_batt_info aaa\n");
    buffer->batt_tempRAW = htc_battery_temperature_lut( av_index );
    if ( buffer->batt_tempRAW < 250 ) /* fixed til so long we can get constant values - otherwise the algo wouln'T work good */
            buffer->batt_tempRAW = 250;
  BATT("htc_get_batt_info bbb\n");
    fix_batt_values(buffer);
  BATT("htc_get_batt_info ccc\n");
    htc_battery_level_compute( buffer );
  BATT("htc_get_batt_info ddd\n");
    return 0;

HeroC battery driver, many different, https://raw.github.com/TeamICS/heroc.../htc_battery.c
Our battery chip is ds2746, same as HD2?
