... here - why do you have firmware in both places?


	In multipd model, Q6 & WCSS uses different firmware.
	I will correct the firmware-name. Thanks for catching.

This compatible is confusing for this device.

	I will clean up all SOC specific compatibles and have
	only device specific compatibles for Q6 & WCSS radio's
	as i mentioned on other thread.

Thanks & Regards,
Manikanta.
