From: Arend van Spriel Date: Tue, 6 Nov 2012 00:22:32 +0000 (-0800) Subject: brcmfmac: use struct brcmf_if parameter in firmware event callbacks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1993732e3bf9df032ea7582409be4f22d257a874;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git brcmfmac: use struct brcmf_if parameter in firmware event callbacks Firmware events are passed to wl_cfg80211 module associated with the primary net device. With virtual interface support events can be received for different interfaces, ie. struct brcmf_if instances. Pass it in the event to determine appropriate net device associated with the event.
