mtd: rawnand: silence static checker warning in nand_setup_interface()
Smatch complains that the error code is not set on this error path:
drivers/mtd/nand/raw/nand_base.c:842 nand_setup_interface()
warn: missing error code 'ret'
But actually returning success is intentional because the NAND chip will
still work in mode 0. This patch adds a "ret = 0;" assignment to make
the intent more clear and to silence the static checker warning. It
doesn't affect the compiled code because GCC optimises the assignment
away.
