Subject: radeon: realloc dma if needed after revalidate
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9b1efcb87c794ded9306f01336d48a80aaad3261;p=mesa.git

radeon: realloc dma if needed after revalidate

Revalidate can trigger flushing and dma buffer deallocation,
so retry allocation on such case.
