I'll add it to the commit log. I'll also fix the typo "condtion" in the title.

But please do not drop the lists, otherwise patchwork won't see this.

The firmware advertises the LDPC support information for HT in HT capability info in the wmi service ready event. To provide granularity, firmware now advertises WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC separately. To support LDPC, host should also check for WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC in HT capabilities. Add a condition to existing logic in host to know whether firmware supports LDPC or not.
