Subject: gallium: remove redundant nr_components field from pipe_vertex_element
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=464a72dd4154f314e08c9d0c4d07417e2bf255f0;p=mesa.git

gallium: remove redundant nr_components field from pipe_vertex_element

This is a property of the associated src_format pipe format.
Hence use util_format_get_nr_components to query this when necessary instead.
