+ * Some ideapads have a hardware rfkill switch, but most do not have one.
+ * Reading VPCCMD_R_RF always results in 0 on models without a hardware rfkill,
+ * switch causing ideapad_laptop to wrongly report all radios as hw-blocked.
+ * There used to be a long list of DMI ids for models without a hw rfkill
+ * switch here, but that resulted in playing whack a mole.
+ * More importantly wrongly reporting the wifi radio as hw-blocked, results in
+ * non working wifi. Whereas not reporting it hw-blocked, when it actually is
+ * hw-blocked results in an empty SSID list, which is a much more benign
+ * failure mode.
+ * So the default now is the much safer option of assuming there is no
+ * hardware rfkill switch. This default also actually matches most hardware,
+ * since having a hw rfkill switch is quite rare on modern hardware, so this
+ * also leads to a much shorter list.
