Merge tag 'nand/fixes-for-4.9-rc3' of github.com:linux-nand/linux
From Boris:
"""
Three simple fixes:
- the first one is fixing a non-critical bug in the gpmi driver
- the second one is fixing a bug in the 'automatic NAND timings
selection' feature introduced in 4.9-rc1
- the last one is fixing a false positive uninitialized-var warning
"""
