Hello Palash Bandyopadhyay,
The patch 02b20b0b4cde: "V4L/DVB (12730): Add conexant cx25821
driver" from Sep 15, 2009, leads to the following warning:
drivers/media/video/cx25821/cx25821-i2c.c:310 cx25821_i2c_register()
error: memcpy() '&cx25821_i2c_algo_template' too small (24 vs 64)
306 dprintk(1, "%s(bus = %d)\n", __func__, bus->nr);
307
308 memcpy(&bus->i2c_adap, &cx25821_i2c_adap_template,
309 sizeof(bus->i2c_adap));
> 310 memcpy(&bus->i2c_algo, &cx25821_i2c_algo_template,
311 sizeof(bus->i2c_algo));
312 memcpy(&bus->i2c_client, &cx25821_i2c_client_template,
313 sizeof(bus->i2c_client));
314
The problem is that "bus->i2c_algo" is a i2c_algo_bit_data struct and
cx25821_i2c_algo_template is a i2c_algorithm struct. They are different
sizes and the function pointers don't line up at all. I don't see how
this can work at all.
regards,
dan carpenter
