Description
In the Linux kernel, the following vulnerability has been resolved:
serial: Fix potential null-ptr-deref in mlb_usio_probe()
devm_ioremap() can return NULL on error. Currently, mlb_usio_probe()
does not check for this case, which could result in a NULL pointer
dereference.
Add NULL check after devm_ioremap() to prevent this issue.
