[PATCH] I2C: Kill i2c_algorithm.id (2/7)
Use the adapter id rather than the algorithm id to detect the i2c-isa pseudo-adapter. This saves one level of dereferencing, and the algorithm ids will soon be gone anyway. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
