rivafb/nvidiafb: Various cleanups
Various cleanups to rivafb/nvidiafb's I2C code:
* Drop useless par->bus.
* Refactor I2C bus deletion code.
* Drop useless variable initialization.
* Remove unneeded include of <linux/i2c-id.h>.
* Simplify +1/-1.
* Add __devinit tags where possible.
[adaplas]
The varible initialization are not useless. However, rivafb must
check if i2c bus are created properly before reading the EDID
block.
