A fix is available — apply it.

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

scsi: csiostor: Fix dereference of null pointer rn

The error exit path when rn is NULL ends up deferencing the null pointer rn via the use of the macro CSIO_INC_STATS. Fix this by adding a new error return path label after the use of the macro to avoid the deference.
