  mtd: docg3: Fix kasprintf() usage (2015-06-16 18:58:47 -0700)

----------------------------------------------------------------
MTD fixes for 4.2

JFFS2

 * fix a theoretical unbalanced locking issue; the lock handling was a bit
   unclean, but AFAICT, it didn't actually lead to real deadlocks

NAND

 * brcmnand driver: new driver supporting NAND controller found originally on
   Broadcom STB SoCs (BCM7xxx), but now also found on BCM63xxx, iProc (e.g.,
   Cygnus, BCM5301x), BCM3xxx, and more

 * Begin factoring out BBT code so it can be shared between traditional
   (parallel) NAND drivers and upcoming SPI NAND drivers (WIP)

 * Add common DT-based init support, so nand_base can pick up some flash
   properties automatically, using established common NAND DT properties

 * mxc_nand: support 8-bit ECC

 * pxa3xx_nand:
   - fix build for ARM64
   - use a jiffies-based timeout

SPI NOR

 * Add a few new IDs

 * Clear out some unnecessary entries

 * Make sure SECT_4K flags are correct for all (?) entries

Core

 * Fix mtd->usecount race conditions (BUG_ON())

 * Switch to modern PM ops

Other

 * CFI: save code space by de-inlining large functions

 * Clean up some partition parser selection code across several drivers

 * Various miscellaneous changes, mostly minor
