Switch to\ndevm_kzalloc() to ensure the memory is managed and freed automatically\nwhen the device is removed.\n\nThe caller of report_fixup() does not take ownership of the returned\npointer, but it is permitted to return a pointer whose lifetime is at\nleast that of the input buffer.\n\nAlso fix a harmless out-of-bounds read by copying only the original\ndescriptor size."
