I need/want to run i2c from CVS (because I need lm_sensors from CVS in order to support my motherboard) but once those patches are applied to the kernel, it breaks compilation of all the v4l drivers (and at least one framebuffer driver, possibly other components.) I have been using 2.4.21-rc7-ac1, but 2.4.21 is just out and appears the same so I'm sure this still applies. I managed to mangle bttv-if.c and tvmixer.c such that it compiles and it even seems to run fine co-existing peacefully with i2c/lm_sensors. However, I'm pretty sure what I did was bad, perhaps someone could comment on how bad? Are there plans to update the v4l drivers to use the new i2c? I imagine doing so before i2c is released (probably as 2.8.0) is not on anyone's todo list. Anyway, what I changed was in bttv-if.c I commented out this in the initialization of bttv_i2c_adap_template: .inc_use = bttv_inc_use, .dec_use = bttv_dec_use, In tvmixer.c I removed these bits: if (client->adapter->inc_use) client->adapter->inc_use(client->adapter); if (client->adapter->dec_use) client->adapter->dec_use(client->adapter); Could anyone fill me in on what the above code does? Does it simply increment the usage count for the module (bttv, or i2c-core or what?) Thanks, Aran
