This goto is wrong. It calls parser_done(ctx) when it should just call
kfree(ctx). The difference is that parser_done() looks like this:
289 static void parser_done(struct parser_context *ctx)
290 {
291 chipset_dev->controlvm_payload_bytes_buffered -=
ctx->param_bytes;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
We never incremented this so we shouldn't be decrementing it.
292 kfree(ctx);
293 }
