commit 133b2acee3 upstream.
At least on the HP Envy x360 15-cp0xxx model the WMI interface
for HPWMI_FEATURE2_QUERY requires an outsize of at least 128 bytes,
otherwise it fails with an error code 5 (HPWMI_RET_INVALID_PARAMETERS):
Dec 06 00:59:38 kernel: hp_wmi: query 0xd returned error 0x5
We do not care about the contents of the buffer, we just want to know
if the HPWMI_FEATURE2_QUERY command is supported.
This commits bumps the buffer size, fixing the error.
Fixes: 8a1513b493 ("hp-wmi: limit hotkey enable")
