Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-16 18:20:36 -04:00			`#ifndef __INCLUDED_TEA6420__`

V4L/DVB (3548): Renamed I2C_foo addresses to I2C_ADDR_foo I2C_foo were used for some i2c addresses. Bad, since those constants could mean other i2c chip things. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org> 2006-03-18 06:31:34 -05:00			`#define I2C_ADDR_TEA6420_1 0x4c`
