Description

In the Linux kernel, the following vulnerability has been resolved:

spi: sn-f-ospi: Fix division by zero

When there is no dummy cycle in the spi-nor commands, both dummy bus cycle bytes and width are zero. Because of the cpu's warning when divided by zero, the warning should be avoided. Return just zero to avoid such calculations.
