[PATCH] mtd: spi-nor: Lower the priority of the software reset failure message

[Michael Walle]

Hi,

This is not really expected. What driver is this? Let me guess, the 
intel
SPI driver.

Please mention this in the commit message.

What is the value of ret here? Ideally it should be -EOPNOTSUPP and then
don't print this message at all. Otherwise leave it at dev_warn(). Also,
please add a comment here.
