[dm-devel] [PATCH] libmultipath: fix printing native nvme multipath topology.

[Benjamin Marzinski]

Since commit 2f05df4 ("libmultipath: use strbuf in print.c"), when
multipath prints the topology of native nvme devices, instead of
printing the multipath device information, it prints "w [G]:d s". This
is because nvme_style() switched from calling snprintf(), which supports
format specifiers, to append_strbuf_str(), which doesn't, while still
keeping the same string, "%%w [%%G]:%%d %%s". Remove the extra percent
signs, since they don't need to be escaped in append_strbuf_str().

Fixes: 2f05df4 ("libmultipath: use strbuf in print.c")
