Since I2C_HW_B_HDPVR is not actually set anywhere and because it's staging, I'd
propose that we just ignore this. It's under an #ifdef, so removing i2c-id.h
will
not affect this code.

This can be removed.

So after my pending tvaudio/tda8425 patch goes in and your patches, then the
only
remaining user of I2C_HW_B_ is lirc_i2c.c, right? Jean will like that :-)
Jean, I did a grep of who is still including i2c-id.h (excluding media drivers):
drivers/gpu/drm/nouveau/nouveau_i2c.h:#include <linux/i2c-id.h>
drivers/gpu/drm/radeon/radeon_mode.h:#include <linux/i2c-id.h>
drivers/gpu/drm/i915/intel_drv.h:#include <linux/i2c-id.h>
drivers/gpu/drm/i915/intel_i2c.c:#include <linux/i2c-id.h>
drivers/video/i810/i810.h:#include <linux/i2c-id.h>
drivers/video/intelfb/intelfb_i2c.c:#include <linux/i2c-id.h>
drivers/video/savage/savagefb.h:#include <linux/i2c-id.h>
drivers/video/aty/radeon_i2c.c:#include <linux/i2c-id.h>
drivers/i2c/busses/i2c-s3c2410.c:#include <linux/i2c-id.h>
drivers/i2c/busses/i2c-pxa.c:#include <linux/i2c-id.h>
drivers/i2c/busses/i2c-ibm_iic.c:#include <linux/i2c-id.h>
AFAIK none of these actually need this include. It's probably a good idea for
you to remove together with this obsolete I2C_HW_B_RIVA:
drivers/video/riva/rivafb-i2c.c: chan->adapter.id =
I2C_HW_B_RIVA;

Hans
