From 1684a984303abbfc39aa8b59b0fe825c717811a9 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 11 Aug 2005 23:51:10 +0200 Subject: [PATCH] [PATCH] I2C: Kill i2c_algorithm.id (6/7) In theory, there should be no more users of I2C_ALGO_* at this point. However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id. We are really lucky that the few other adapters we want this driver to work with did not fulfill that condition.
