These series patch correct the behaviour of
flash_get_info() function defined in drivers/mtd/cfi_flash.c
I separated a cosmetic change in the first patch.

When base address given was out of valid flash address ranges,
flash_get_info() function returned the pointer to the last
element of flash_info[i] array.
This patch changes this function to return NULL pointer
in such a case, which is more correct behaviour.
The function flash_protect_default() calls flash_protect()
immediately after flash_get_info() invocation.
With this correction, flash_protect() function would be
able to return soon, for NULL flash_info.
