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.
