Try changing one thing at a time per patch please.
There's some bugs in here:
- struct config_t dig_in_config[32];
- struct config_t dig_out_config[32];
- struct config_t chan_in_config[32];
- struct config_t chan_out_config[32];
int i;
+ config_data = kmalloc(sizeof(struct config_data_t), GFP_KERNEL);
Shouldn't that be:
config_data = kmalloc(sizeof(struct config_data_t)*32, GFP_KERNEL);
The structure already has the [32]'s copied from the original defn's.
If you like... I can still break up the commit into two patches. Also,
moving the *32 out isn't a bad idea; were I
to break it up, I would likely do so.
Otherwise you overflow your buffer here:
for (i = 0; i < 32; i++) {
- dig_in_config[i].kind = 0;
- dig_in_config[i].bits = 0;
- dig_in_config[i].min = 0;
- dig_in_config[i].max = 0;
- dig_out_config[i].kind = 0;
- dig_out_config[i].bits = 0;
- dig_out_config[i].min = 0;
- dig_out_config[i].max = 0;
- chan_in_config[i].kind = 0;
- chan_in_config[i].bits = 0;
- chan_in_config[i].min = 0;
- chan_in_config[i].max = 0;
- chan_out_config[i].kind = 0;
- chan_out_config[i].bits = 0;
- chan_out_config[i].min = 0;
- chan_out_config[i].max = 0;
+ config_data->dig_in_config[i].kind = 0;
+ config_data->dig_in_config[i].bits = 0;
+ config_data->dig_in_config[i].min = 0;
+ config_data->dig_in_config[i].max = 0;
+ config_data->dig_out_config[i].kind = 0;
+ config_data->dig_out_config[i].bits = 0;
+ config_data->dig_out_config[i].min = 0;
+ config_data->dig_out_config[i].max = 0;
+ config_data->chan_in_config[i].kind = 0;
+ config_data->chan_in_config[i].bits = 0;
+ config_data->chan_in_config[i].min = 0;
+ config_data->chan_in_config[i].max = 0;
+ config_data->chan_out_config[i].kind = 0;
+ config_data->chan_out_config[i].bits = 0;
+ config_data->chan_out_config[i].min = 0;
+ config_data->chan_out_config[i].max = 0;
}
Or am I mistaken?
thanks,
