Fix up various trivial conflicts, largely due to changes in calling conventions for things like dmaengine_prep_slave_sg() (new inline wrapper to hide new parameter, clashing with rewrite of previously last parameter that used to be an 'append' flag, and is now a bitmap of 'unsigned long flags'). (Also some header file fallout - like so many merges this merge window - and silly conflicts with sparse fixes) * tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6: (120 commits) mtd: docg3 add protection against concurrency mtd: docg3 refactor cascade floors structure mtd: docg3 increase write/erase timeout mtd: docg3 fix inbound calculations mtd: nand: gpmi: fix function annotations mtd: phram: fix section mismatch for phram_setup mtd: unify initialization of erase_info->fail_addr mtd: support ONFI multi lun NAND mtd: sm_ftl: fix typo in major number. mtd: add device-tree support to spear_smi mtd: spear_smi: Remove default partition information from driver mtd: Add device-tree support to fsmc_nand mtd: fix section mismatch for doc_probe_device mtd: nand/fsmc: Remove sparse warnings and errors mtd: nand/fsmc: Add DMA support mtd: nand/fsmc: Access the NAND device word by word whenever possible mtd: nand/fsmc: Use dev_err to report error scenario mtd: nand/fsmc: Use devm routines mtd: nand/fsmc: Modify fsmc driver to accept nand timing parameters via platform mtd: fsmc_nand: add pm callbacks to support hibernation ...
