mfd: ab8500-debugfs: Apply a check for -ENOMEM after allocating memory for sysfs The AB8500 debugfs driver allocates memory for 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 NULL->[show|store|...], which would obviously cause a pointer dereference Oops. Signed-off-by: Lee Jones <lee.jones@linaro.org>
