mtd: spi-nor.c: wrong test in stm_unlock()

[Giorgio]

Hi,

I noticed a wrong test within the function stm_unlock() in spi-nor.c in
the kernel 4.6-rc5:

static int stm_unlock(struct spi_nor *nor, loff_t ofs, uint64_t len)
{
	struct mtd_info *mtd = &nor->mtd;
	int status_old, status_new;
	u8 mask = SR_BP2 | SR_BP1 | SR_BP0;
...
...
	/* Don't protect status register if we're fully unlocked */
	if (lock_len == mtd->size)
		status_new &= ~SR_SRWD;
...

This last if test should be:

	if (lock_len == 0)
		status_new &= ~SR_SRWD;
