Some "#ifdef CONFIG_OF"s are missing:

drivers/mtd/chips/cfi_cmdset_0002.c: In function ‘cfi_cmdset_0002’:
drivers/mtd/chips/cfi_cmdset_0002.c:579:4: error: implicit declaration of function ‘of_property_read_bool’ [-Werror=implicit-function-declaration]
drivers/mtd/chips/cfi_cmdset_0002.c: In function ‘do_read_secsi_onechip’:
drivers/mtd/chips/cfi_cmdset_0002.c:1146:16: warning: variable ‘timeo’ set but not used [-Wunused-but-set-variable]
cc1: some warnings being treated as errors
make[4]: *** [drivers/mtd/chips/cfi_cmdset_0002.o] Error 1

Please, check allso the timeo warning.
