Hi Marcelo, This patch fixes the bus reset in i2c-philips-par when it is loaded with type!=0. For now, the reset is always made as if type==0. This patch was built and tested on 2.4.25-pre7. I've committed a similar fix to our i2c CVS repository, and have sent a patch to Greg KH for 2.6 too, which he already accepted. This is a bug fix, however: * I think that the i2c-philips-par driver isn't much used. * I think that the i2c-philips-par driver with type!=0 is even less used. * The bus reset is more or less optional. Skipping it doesn't hurt much. * The wrong reset doesn't hurt either. So this is in no way critical (and explains why the bug wasn't discovered earlier). On the other hand the fix is easy and clear. Anyway I leave it to you to decide if it should be applied to 2.4 or not. Thanks. --- linux-2.4.25-pre7/drivers/i2c/i2c-philips-par.c.orig Sun Jan 25 09:57:06 2004 +++ linux-2.4.25-pre7/drivers/i2c/i2c-philips-par.c Sun Jan 25 09:59:36 2004 @@ -212,8 +212,8 @@ /* reset hardware to sane state */ parport_claim_or_block(adapter->pdev); - bit_lp_setsda(port, 1); - bit_lp_setscl(port, 1); + adapter->bit_lp_data.setsda(port, 1); + adapter->bit_lp_data.setscl(port, 1); parport_release(adapter->pdev); if (i2c_bit_add_bus(&adapter->adapter) < 0) -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
