The i2c-pxa driver changes have only been compile-tested and are just for cleanup purposes. Changes in v4: - Rebased atop the removal of MAX_IDR_MASK. Changes in v3: - Addressed Wolfram's feedback; rebased atop idr-cleanup series. Changes in v2: - No longer tweak pdev->id as per Sylwester Nawrocki. - No longer add the dev ID to the adap.name. Other drivers don't include the device ID here and it doesn't make sense with dynamically (or automatically) allocated IDs. - Use dev_name(&dev->dev) to register for the IRQ; this matches what the i2c-s3c2410.c does and handles dynamically allocated IDs. - This change was only compile-tested (corgi_defconfig), since I don't have access to a board that uses this driver.
