From: Arend Van Spriel Date: Thu, 22 Mar 2018 20:28:28 +0000 (+0100) Subject: brcmfmac: add extension to .get_fwname() callbacks X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=bf7a7b37f6ef5090a2bae7e7ae23cd26b741cca4;p=openwrt%2Fstaging%2Fblogic.git brcmfmac: add extension to .get_fwname() callbacks This changes the bus layer api by having the caller provide an extension. With this the callback can use brcmf_fw_alloc_request() to get the needed firmware name.
