Merge tag 'nand/for-4.11' of github.com:linux-nand/linux
From Boris: """ This pull request contains minor fixes/improvements on existing drivers: - sunxi: avoid busy-waiting for NAND events - ifc: fix ECC handling on IFC v1.0 - OX820: add explicit dependency on ARCH_OXNAS in Kconfig - core: add a new manufacture ID and fix a kernel-doc warning - fsmc: kill pdata support - lpc32xx_slc: remove unneeded NULL check """ Conflicts: include/linux/mtd/nand.h [Brian: trivial conflict in the comment section]
