Subject: util: Use util_is_power_of_two_nonzero in u_vector
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd18aa1e50e4668c8d992816bcdb74376dd1064c;p=mesa.git

util: Use util_is_power_of_two_nonzero in u_vector

Previously size=0, element_size=0 would have been allowed.  That
combination can only lead to despair.
