http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=commit;h=a531257c40920de0161150091eaccbbc1182eb96 It seems Broadcom wants using some basename-apiversion syntax for their firmware files... but indeed it does not make much sense to me. According to their firmware, current API is 0. I assume it from reading file name which is bcm43xx-0.fw. It does not make much sense, as we had at least 2 earlier APIs. Looks like dead end. Don't know what else we can propose. Putting exact version and patchlevel will make it complex (a lot of firmwares are available). -- Rafał _______________________________________________ b43-dev mailing list b43-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/b43-dev
