Title
scsi: myrs: Fix crash in error case
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: myrs: Fix crash in error case In myrs_detect(), cs->disable_intr is NULL when privdata->hw_init() fails with non-zero. In this case, myrs_cleanup(cs) will call a NULL ptr and crash the kernel.
