[ Upstream commit 998b5a78a9ce1cc4378e7281e4ea310e37596170 ]
Commit 120584c728a6 ("hwmon: (aquacomputer_d5next) Add support for Octo flow sensor") added support for reading Octo flow sensor, but didn't update the priv->speed_input array length. Since Octo has 8 fans, with the addition of the flow sensor the proper length for speed_input is 9.
Reported by Arne Schwabe on Github [1], who received a UBSAN warning.
