Description dcb314 2017-08-21 16:56:02 UTC
mesa-17.1.7/src/gallium/auxiliary/pipebuffer/pb_cache.c:169]: (style) Suspicious condition (assignment + comparison); Clarify expression with parentheses.

Source code is

      if (!entry && (ret = pb_cache_is_buffer_compat(cur_entry, size,
                                                     alignment, usage) > 0))

maybe better code

      if (!entry && ((ret = pb_cache_is_buffer_compat(cur_entry, size,
                                                     alignment, usage)) > 0))

    gallium/pipebuffer: fix parenthesis location
    
    Without this the return value will never get set to -1. This
    was first added in 49866c8f3457 and copied in 2b396eeed983.
    
    Fixes: 2b396eeed983 "gallium/pb_cache: add a copy of cache bufmgr independent of pb_manager"
