Merge branch 'linux-next' of git://git.infradead.org/ubi-2.6
* 'linux-next' of git://git.infradead.org/ubi-2.6: UBI: switch to dynamic printks UBI: turn some macros into static inline UBI: improve checking in debugging prints UBI: fix typo in a message UBI: fix minor stylistic issues UBI: use __packed instead of __attribute__((packed)) UBI: cleanup comments around volume properties UBI: re-name set volume properties ioctl UBI: make the control character device non-seekable
