Subject: ggml : remove redundant n_copies check when setting input/output (#17612)
X-Git-Tag: upstream/0.0.7446~211
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=7f3a72a8ed796a135c81903546ef57c4aeda9f06;p=pkg%2Fggml%2Fsources%2Fllama.cpp

ggml : remove redundant n_copies check when setting input/output (#17612)

This commit removes a redundant check for sched->n_copies > 1 when
setting input and output flags on tensor copies in
ggml_backend_sched_split_graph.

The motivation for this change is to clarify the code as the outer if
statement already performs this check.
