Merge branch 'akpm' (incoming from Andrew)
Merge second batch of fixes from Andrew Morton: - various misc bits - some printk updates - a new "SRAM" driver. - MAINTAINERS updates - the backlight driver queue - checkpatch updates - a few init/ changes - a huge number of drivers/rtc changes - fatfs updates - some lib/idr.c work - some renaming of the random driver interfaces * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (285 commits) net: rename random32 to prandom net/core: remove duplicate statements by do-while loop net/core: rename random32() to prandom_u32() net/netfilter: rename random32() to prandom_u32() net/sched: rename random32() to prandom_u32() net/sunrpc: rename random32() to prandom_u32() scsi: rename random32() to prandom_u32() lguest: rename random32() to prandom_u32() uwb: rename random32() to prandom_u32() video/uvesafb: rename random32() to prandom_u32() mmc: rename random32() to prandom_u32() drbd: rename random32() to prandom_u32() kernel/: rename random32() to prandom_u32() mm/: rename random32() to prandom_u32() lib/: rename random32() to prandom_u32() x86: rename random32() to prandom_u32() x86: pageattr-test: remove srandom32 call uuid: use prandom_bytes() raid6test: use prandom_bytes() sctp: convert sctp_assoc_set_id() to use idr_alloc_cyclic() ...
