[PATCH] mtd: rawnand: silence static checker warning in nand_setup_interface()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
