Subject: [PATCH 06/34] brcmfmac: firmware: Support passing in multiple board_types
Date: Mon, 27 Dec 2021 00:35:56 +0900	[thread overview]
Message-ID: <20211226153624.162281-7-marcan@marcan.st> (raw)
In-Reply-To: <20211226153624.162281-1-marcan@marcan.st>

In order to make use of the multiple alt_path functionality, change
board_type to an array. Bus drivers can pass in a NULL-terminated list
of board type strings to try for the firmware fetch.

Signed-off-by: Hector Martin <marcan@marcan.st>
