Summary
scsi: qedi: Fix crash while reading debugfs attribute
Details

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

scsi: qedi: Fix crash while reading debugfs attribute

The qedidbgdonotrecovercmdread() function invokes sprintf() directly on a __user pointer, which results into the crash.

To fix this issue, use a small local stack buffer for sprintf() and then call simplereadfrombuffer(), which in turns make the copyto_user() call.
