Description
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: add missing discipline function
Fix crash with illegal operation exception in dasd_device_tasklet.
Commit b72949328869 ("s390/dasd: Prepare for additional path event handling")
renamed the verify_path function for ECKD but not for FBA and DIAG.
This leads to a panic when the path verification function is called for a
FBA or DIAG device.
Fix by defining a wrapper function for dasd_generic_verify_path().
