Subject: radv: check CS space in radv_emit_write_data_packet()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c08ae911d9a6e4d327fd1fb5316edd093e8d245b;p=mesa.git

radv: check CS space in radv_emit_write_data_packet()

This wasn't wrong but it looks better to me like this. It's
only used for debugging purposes (ie. RADV_TRACE_FILE).
