Merge branch 'at91-fixes-for-linus' of git://github.com/at91linux/linux-2.6-at91
* 'at91-fixes-for-linus' of git://github.com/at91linux/linux-2.6-at91: AT91: at91sam9261ek: remove C99 comments but keep information AT91: at91sam9261ek board: remove warnings related to use of SPI or SD/MMC AT91: dm9000 initialization update AT91: SAM9G45 - add a separate clock entry for every single TC block AT91: clock: peripheral clocks can have other parent than mck AT91: change dma resource index
