[PATCH] firmware: fix BUG: in fw_realloc_buffer
The fw_realloc_buffer routine does not handle an increase in buffer size of more than 4k. It's not clear to me why it expects that it will only get an extra 4k of data. The attached patch modifies fw_realloc_buffer to vmalloc as much memory as is requested, instead of what we previously had + 4k. I've tested this on my laptop, which would crash occaisionally on boot without the patch. With the patch, it hasn't crashed, but I can't be certain that this code path is exercised.
