Subject: [PATCH 5.10 101/199] platform/x86: hp-wmi: Dont log a warning on HPWMI_RET_UNKNOWN_COMMAND errors

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit d35c9a029a73e84d84337403d20b060494890570 ]

The recently added thermal policy support makes a
hp_wmi_perform_query(0x4c, ...) call on older devices which do not
support thermal policies this causes the following warning to be
logged (seen on a HP Stream x360 Convertible PC 11):

[   26.805305] hp_wmi: query 0x4c returned error 0x3

Error 0x3 is HPWMI_RET_UNKNOWN_COMMAND error. This commit silences
the warning for unknown-command errors, silencing the new warning.
