Subject: [PATCH] asus-laptop: fix a memory leak in asus_laptop_get_info error
 path

The callers of write_acpi_int_ret() pass ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.

This patch adds a missing kfree(buffer.pointer) before return -ENOMEM
if kstrdup fail.
