Hence I separated the stuff to own _lo > and _hi functions. Hmm. I was thinking of something like static void bd79124_re_enable_xx(struct bd79124_data *data, unsigned int channel, unsigned int reg, u16 limit, enum iio_event_dir dir) { int ret, evbit = BIT(dir); if (!(data->alarm_suppressed[channel] & evbit)) return; data->alarm_suppressed[channel] &= (~evbit); if (!(data->alarm_monitored[channel] & evbit)) return; ret = bd79124_write_int_to_reg(data, reg, limit); if (ret) dev_warn(data->dev, "Low limit enabling failed for channel%d\n", channel); } static void bd71924_reenable_hi(struct bd79124_data *data, unsigned int channel) { return bd71924_reenable_x(data, channel, BD79124_GET_HIGH_LIMIT_REG(channel) data->alarm_r_limit[channel], IIO_EV_DIR_RISING); } static void bd71924_reenable_lo(struct bd79124_data *data, unsigned int channel) { return bd71924_reenable_x(data, channel, BD79124_GET_LOW_LIMIT_REG(channel) data->alarm_f_limit[channel], IIO_EV_DIR_FALLING); } But I guess not really a saving in the end. > > > >> + > >> + ret = bd79124_write_int_to_reg(data, BD79124_GET_HIGH_LIMIT_REG(channel), > >> + data->alarm_r_limit[channel]); > >> + if (ret) > >> + dev_warn(data->dev, "High limit enabling failed for channel%d\n", > >> + channel); > >> +} > > > > Yours, > -- Matti > >
