mfd: ab8500-debugfs: Apply a check for -ENOMEM after allocating memory for event name
The AB8500 debugfs driver allocates memory to contain the name of a new sysfs entry, but fails to apply the proper post-allocation checks. If the device were to run out of memory, the allocation would return NULL. Without the correct checks the driver will continue to populate address NULL with the specified device name which would obviously cause a pointer dereference Oops.
