Fixed the subject to "i2c: pxa-pci:" and fixed this checkpatch warning:

WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: 7e94dd154e93 ("i2c-pxa2xx: Add PCI support for PXA I2C controller")'
#3:
Fixes: 7e94dd154e934 ("i2c-pxa2xx: Add PCI support for PXA I2C controller")

Please do that in the future. After all that, applied to for-next, thanks!
